September 3, 1929, Transcontinental Air Transport (T.A.T.) Ford 5-AT-B Tri-Motor (NC9649) Mt. Taylor, NM : ACCIDENT SYNOPSIS: On the morning of Tuesday September 3, 1929, a Ford Tri-Motor departed Albuquerque's main passenger air field en route to Los Angeles, California. On board were five passengers, two pilots, and a courier. For pioneering airline Transcontinental Air Transport (T.A.T.) today's flight would be considered routine having a few months prior inaugurated 48 hour coast-to-coast service from New York to Los Angeles. The service was unique in that traveling passengers would take trains operated by the Pennsylvania Railroad and Santa Fe Railroad to travel at night by Pullman car and then board one of T.A.T.'s Ford Tri-Motor aircraft during the day to continue their trip. Air travel at the time was a new concept for many and well known aviation pioneers such as Charles Lindbergh and Amelia Earhart were hired as paid consultants to build public confidence and acceptance. Lindbergh himself having flown and approving the transcontinental routes that T.A.T. would fly. This was the beginning of passenger airline travel. The weather west of Albuquerque was dark with thunder clouds and rain as the flight made it's way toward Winslow, Arizona. The Ford 5-AT-B Tri-Motor (NC9649) named by the airline; "City of San Francisco" and was delivered to T.A.T. less than one year prior. The T.A.T. flight crew consisted of Captain J.B. Stowe and Co-Pilot E.A. Dietel. T.A.T. Courier C.F. Canfield attended to the five passengers. With just over 45 minutes passed into the stormy flight, the "City of San Francisco" had diverted north of course and into mountainous terrain of Mt. Taylor near Grants, New Mexico. Whether it was low visibility, strong downdrafts or a fatal combination of both, the answers to what really happened to the flight has been lost to the passage of nearly eighty years. What we do know is that the "City of San Francisco" along with it's compliment of passengers and crew came to a violent end on the tree covered slopes of Mt. Taylor. For T.A.T. officials and the rest of the world, the flight had simply vanished without a trace. Searchers, many of them local volunteers spent long hours in the air and on foot looking for the lost aircraft. It would be nearly four days before the wreckage of T.A.T. Flight A19 was discovered. This accident is considered to be one of the first commercial airline disasters and at the time it was believed that this accident would end passenger air travel. *********************************************************************************************************************************** HISTORICAL SUMMARY: Researching and visiting this accident site was a great opportunity. In late 2008, I was notified that the United States Forest Service (USFS) in New Mexico was seeking volunteers to help document a few historical aircraft accident sites near Grants. One of which was the crash site of the "City of San Francisco". The work involved was part of the USFS's "Passports in Time" (PIT) program. I couldn't resist and had to sign up. I was drawn to this particular crash site by the amazing story and the time period that the accident occurred. At nearly 80 years old, this was earliest crash site that I ever had the opportunity to visit and document. What also made this accident intriguing to me was that the aircraft involved was the same exact model that I currently fly for the Planes of Fame Air Museum in Valle, Arizona. During June 2009, we began survey and excavation work on the site. Along with project leader and archaeologist Linda Popelish of the USFS, were several people from the aviation archaeology community. Both groups worked very well with one another as ideas and field techniques were shared. Thank you for viewing the following story and photos.

October 17, 1937, United Air Lines, Inc., Douglas DC-3A (NC16074) Humpy Ridge, UT : ACCIDENT SYNOPSIS: United Air Lines Trip One was a scheduled transcontinental flight that originated in Newark, New Jersey. After making several stops, the flight landed in Cheyenne, Wyoming at which point the aircraft were swapped. Flying the remainder of the flight to Salt Lake City would be Douglas DC3A (NC16074). It was 6:26 PM on October 17th when Trip One departed Cheyenne with 16 passengers and a crew of 3. The weather en-route consisted of low overcast conditions with rain and snow flurries in the higher elevations. The weather was not a concern for Captain Earl D. Woodgerd who was a veteran flier with 11,000 hours of flight time and three years of experience flying the Cheyenne to Salt Lake City route. Assisting Woodgerd was Co-Pilot John B. Adams with 3,500 hours of flight time. A third member of the crew was Miss Leah Derr who served as the flight's Stewardess. In spite of the bad weather, a correction was made on the flight plan changing the previous entry of "instruments" to "intermittent instruments". The correction would allow the flight to fly under the weather, but not above the hazardous mountainous terrain. The flight, cruising at 10,000 feet, communicated with radio operators at both Knight, Wyoming and Salt Lake which relayed to the flight the deteriorating weather conditions and expected time of arrivals over various positions along the route. At 8:19 PM, United Trip One acknowledged a weather report from Salt Lake. At 9:05 PM, The controllers at Salt Lake made several repeated calls to United Trip One, but there was no response from flight. The subsequent accident investigation revealed that United Trip One had strayed south of the intended course by 20 miles and into the east slope of 10,300 foot Humpy Ridge. All on-board were killed on impact. The cause of the flight's deviation was most likely the result of snow static phenomenon and an un-forecasted shift in wind. *********************************************************************************************************************************** HISTORICAL SUMMARY: Before driving out and hiking to the site, I had the opportunity to fly over the site during 1996 and match an old photo from 1937 with the crash site location. On August 31, 1997 I began my hike to the GPS coordinates I determined to be the impact site. The crash site is remote, so I surprised to find very little wreckage at the site The remaining wreckage at the site consisted of small metal fragments, glass from the passenger windows, and broken dishware china from the aircraft galley. A partially buried fragment caught my eye at the impact point. It was piece of cast metal from the engine case. Undamaged and in like new condition the enameled eagle of the Pratt and Whitney engine logo.

January 16, 1942, Transcontinental & Western Air (TWA), Douglas DC-3 (NC1946) Potosi Mountain, NV : ACCIDENT SYNOPSIS: Transcontinental & Western Air Flight 3, a Douglas DC-3 (NC1946) was a scheduled transcontinental coast to coast flight originating from New York City with the ultimate destination of Burbank/Los Angeles, California. Unlike today's non-stop transcontinental flights, this flight was to make several stops on it's way across the country. One scheduled stop it made in the early morning hours of January 16, 1942 was Indianapolis, Indiana where the flight boarded several passengers including actress Carole Lombard, her mother Elizabeth Peters, and MGM Studio Agent Otto Winkler. Lombard and company had just completed a successful cross-country trip selling two million dollars worth of war bonds to support the war efforts. At 5:27 AM, the flight departed Indianapolis and continued west until it reached St. Louis. Taking on cargo, the flight was delayed nearly two hours by a layer of early morning fog that reduced visibility to less than one quarter of a mile. At 9:03 AM, the fog lifted and the flight continued on with more scheduled stops and strong headwinds. By the time Flight 3 reached Albuquerque, New Mexico it was running more than three hours late. More delays were experienced in Albuquerque as passengers and cargo had to be removed in order to make room for fifteen military pilots and crew who had war time travel priority. Initially, the Lombard trio was removed from the flight, but Carole insisted that their group had priority due to her participation in the war bond tour. The gate agent not wanting to argue with the obviously irritated Lombard, allowed her party to continue their trip. The only other civilian passenger allowed to continue was Mrs. Lois Hamilton. An aircraft crew change also took place in Albuquerque. In command of TWA Flight 3 would be Captain Wayne Williams, Co-pilot Morgan Gillette, and Air Hostess Alice Getz. Under the normal planned route, the flight would have been able to continue direct to its final destination however the extra weight of passengers, cargo and headwinds required an en route fuel stop at Las Vegas, Nevada. At 4:40 PM, Flight 3 departed Albuquerque for the Las Vegas Air Terminal which unlike Boulder City (TWA Terminal) had lighted runways. It was 6:37 PM when Flight 3 reached Las Vegas. This stop was quick. Just enough time to take on more fuel, have passengers stretch their legs, and for Hostess Getz to top off the two galley containers with hot coffee. At 7:07 PM, the flight departed runway 34 and began its climbing left turn across the Las Vegas Valley. The night of January 16th was dark and moonless as the DC-3 leveled off at the cruising altitude of 8,000 feet. The night was made even darker with the government's decision to blackout the lighted airway beacons due to wartime national security threats. With the passenger cabin lights comfortably dimmed, up front in the cockpit, Captain Williams probably had the instrument and cockpit flood lights turned up to set the power for cruise flight. Perhaps Co-pilot Gillette was busy with a navigation chart or trying to confirm their course. Regardless of the reason or task at hand, neither pilot noticed the selected course was sending them into the snow-capped 8,500 foot Potosi Mountain. The collision with the vertical cliff of Potosi Mountain was devastating and all 22 passengers and crew were killed instantly. When the final report was issued nearly a year later, the Civil Aeronautics Board (CAB) investigators were never able to determine why the flight flew off course and into mountainous terrain. *********************************************************************************************************************************** HISTORICAL SUMMARY: It was around 1990 when I started my research of TWA Flight 3. The story of the accident was interesting to me in that it involved many aspects of history, two of which were World War 2 and the other was the "Golden Age" of Hollywood and film. Armed with the CAB Report, newspaper articles, and a couple grainy photos, I had little other help to locate the wreck. I decided the best way to find the crash site was to spot the location from the ground and then from the air. In the next six months I planned my hike carefully and decided the best way to approach the site would be from the south side of the mountain (This was the route used by the recovery teams in 1942). The hike up the mountain was very steep, but I did manage to locate the crash site after a few hours. The site as I first located it during 1991 was relatively pristine with very little foot traffic. Identifiable components such as landing gear and engines were located and documented. It was the smaller items that most people stepped over that proved to be the most revealing in the visits I have made throughout the years. Unfortunately today, the crash site is a publicized hiking trip on the internet and I would guess that it is now visited by hikers every other weekend. When I last visited the site in the early part of 2008, soda cans, bottles and other trash littered the site. In addition, one engine has been rolled down the steep mountain slope by vandals. I still have plans to replace a stolen memorial plaque at the site, but I am hesitant due to possible vandalism. I would like to see the U.S. Forest Service be more pro-active and protect this historical resource from further damage. The crash site itself lies within the Red Rock Canyon National Conservation Area which is managed by both Bureau of Land Management (BLM) and U.S. Forest Service.

October 24, 1947, United Air Lines Inc., Douglas DC-6 (NC37510) Bryce Canyon, UT : ACCIDENT SYNOPSIS: On October 24, 1947, a Douglas DC-6 (NC37510) operating as Flight 608 by United Air Lines departed Los Angeles International Airport for a non-stop flight to Chicago, Illinois. Flight 608 carried 47 passengers and a crew of 5. In command of the flight was Captain Everett McMillen and Co-Pilot George Griesbach. In the back attending to the passengers were stewardesses Helen Morrissey, Shirley Hickey, and Sabina Joswick. At 12:21 PM, Captain McMillen radioed that there was a fire in the baggage compartment which they could not control, with smoke entering the passenger cabin. The flight requested an emergency clearance to Bryce Canyon Airport, Utah, which was granted. As the aircraft descended, pieces of the plane, including portions of the right wing started to fall off. At 12:27 PM, the last radio transmission was heard from the plane: "We may make it - approaching a strip." United Flight 608 had passed over the crest of a tall plateau and was about a mile from the approach end of the runway at Bryce Canyon when the nose of the plane suddenly pitched over. Unable to counteract the loss of control, the aircraft impacted with such force that all four engines were ripped from their mounts and thrown 300 feet beyond the fireball. The airliner crashed onto National Park Service land, killing all 52 passengers and crew on board. The cause of the fire and crash of United flight 608 was a mystery until three weeks later when an American Airlines DC-6 reported an in-flight fire over Arizona. The flight managed to make an emergency landing at Gallup, New Mexico. All 25 occupants escaped the burning plane, and the fire was extinguished. But unlike the Bryce Canyon crash a month earlier, investigators now had a damaged but intact aircraft to examine and study. The cause of both the Bryce Canyon crash and the near-fatal Gallup incident was eventually traced to a design flaw. A cabin heater intake scoop was positioned too close to the number 3 alternate tank air vent. If flightcrews allowed a tank to be overfilled during a routine fuel transfer between wing tanks, it could lead to several gallons of excess fuel being sucked into the cabin heater system, which then ignited the fuel. *********************************************************************************************************************************** HISTORICAL SUMMARY: As it was in 1947, a vacant field marks the crash site of United Flight 608. Less than 100 yards across a fence line designating the Bryce Canyon National Park a visitor will find the small remanants of this air disaster. Only a few fragments remain today since most of the wreckage was loaded onto trucks and moved to Douglas Aircraft Company in California where the plane was reassembled for the accident investigation. The remainder of the site was picked clean over the years by souvenir hunters with very little protection from the National Park Service. Due to it's age, the crash site and what little remains is protected by laws governing the preservation of historical sites.

April 21, 1958, United Air Lines / USAF, Douglas DC-7 (N6328C) / North American F-100F (56-3755) Mid-Air Collision near Las Vegas, NV : ACCIDENT SYNOPSIS: United Air Lines Flight 736, a DC-7 (N6328C), departed with 47 passengers and crew from Los Angeles (LAX) at 7:37 AM. Flight 736 was on a transcontinental flight to New York City (Idlywild) with a planned cruising altitude of 21,000 feet. At about 7:45 AM, a US Air Force North American F-100F-5-NA Super Sabre fighter (56-3755) took off from Nellis AFB on an instrument training flight. During the exercise the flight was executing a simulated jet penetration in the area of Las Vegas, NV. At 8:30 AM, the fighter plane pilot reported that they were descending from 28,000 feet near the KRAM radio station. At the same time, United flight 736 was approaching the Las Vegas VOR. Both aircraft collided head-on at 21,000 feet, nine miles southwest of the Las Vegas VOR station on Victor Airway 8. Initial contact occurred between the leading edge of the DC-7's starboard wing and the leading edge of the F-100's starboard wing. It was determined during the Civil Aeronautics Board (CAB) accident investigation that the DC-7 was flying at about 312 knots on a 023 degree heading and the F-100 at 444 knots on a 145 degree heading. Assuming a small descent angle of the F-100, the closure speed was close to 700 knots. Both planes crashed out of control with the DC-7 entering a steep spiral dive. During the dive, three of the DC-7's four radial engines separated prior to impact. All persons on board both aircraft were killed. ***************************************************************************************************************************** HISTORICAL SUMMARY: The collision created two aircraft impact sites separated by seven miles, in addition to a large debris field between the two sites. During 1995, after much research and an extensive ground search, the DC-7 engine impact site was located. This discovery along with the discovery of the F-100F crash site by Craig Fuller of AAIR allowed the triangulation of the DC-7 main impact site. When we first examined the DC-7 impact site, it appeared to be undisturbed with little evidence that an impact even took place. Reviewing old aerial photos, we decided to dig some test pits which revealed that the site (burned impact area) had been covered with a layer of top soil after the initial recovery work had been completed in 1958. The top soil not only concealed the site, but also formed a protective barrier from exposure. In effect it was a time capsule. However, with the population of Las Vegas growing, it was inevitable that the DC-7 impact site was in the path of future development. Working with the landowner, we adopted a plan to map, excavate, document, and preserve the wreckage material we could recover. Over the following three years we excavated an area about 40 feet by 30 feet using a series of grids to mark not only where we excavated but also help document where we located items of interest. As a result, we recovered and documented hundreds of historical items during the excavations. Within a few short years the crash site of United Air Lines Flight 736 would be replaced by several commercial buildings and homes. **UPDATE** June 2008, I visited the impact site of UAL Flight 736. A backhoe tractor had excavated a series of utility line trenches in front of the auto-tire center that was under construction. Visible in the freshly cut trench walls were the burned remnants of the DC-7 still covered in the top soil from 1958. I returned the next day and the trenches had been filled in.

June 6, 1971, Hughes Air West / USMC, McDonnell Douglas DC-9 (N9345) / McDonnell Douglas F-4B (151458) Mid-Air Collision near Duarte, CA : Hughes Airwest Flight 706, a DC-9, was to fly from Los Angeles, CA (LAX) to Seattle, WA (SEA) with intermediate stops at Salt Lake City (SLC), Boise (BOI), Lewiston (LWS), Pasco (PSC) and Yakima (YKM). The aircraft departed Los Angeles at 18:02. At 18:09 the crew reported leaving 12,000 feet and Los Angeles ARTCC cleared them direct to Daggett. At 17:16, a US Marine Corps McDonnell Douglas F-4B Phantom Bu# 151458 departed Naval Auxiliary Air Station (NAAS) Fallon for a flight to MCAS El Toro at low altitude. The aircraft had several technical difficulties, including an inoperative transponder and a leak in the oxygen system. Due to deteriorating visibility northwest of Palmdale, the crew climbed to 15,500 feet. Shortly after level-off, aircraft was 50 miles from MCAS El Toro. The pilot executed a 360° aileron roll at this time, which took approximately three seconds to complete. The Radar Intercept Officer (RIO) estimated that the true airspeed in the climb and after level-off was 420 knots. At 15,150 feet, the F-4B collided with the Airwest DC-9 about one minute and twenty seconds after the roll. After the collision, the F-4 began to tumble violently about the lateral axis. The RIO waited about 5 seconds and after seeing numerous warning lights in the cockpit, ejected from the aircraft. The ejection was successful and he parachuted to the ground without injury. The F-4B pilot did not survive the accident. PROBABLE CAUSE: The failure of both crews to see and avoid each other but it is recognized that they had only marginal capability to detect, assess, and avoid the collision. Other causal factors include a very high closure rate, comingling of IFR and VFR traffic in an area where the limitation of the ATC system precludes effective separation of such traffic, and failure of the crew of BuNo458 to request radar advisory service, particularly considering the fact that they had an inoperable transponder."

June 29, 2008, Classic Helicopter Services / Guardian Air, Bell 407 (N407MJ) / Bell 407 (N407GA) Mid-Air Collision, Flagstaff, AZ : ACCIDENT SYNOPSIS: On June 29, 2008, at 1547 Mountain Standard Time, a Bell 407 emergency medical service (EMS) helicopter, N407GA, and a Bell 407 EMS helicopter, N407MJ, collided in mid air while approaching the Flagstaff Medical Center helipad (3AZ0), Flagstaff, Arizona. Both helicopters were destroyed. N407GA's commercial pilot, flight nurse, and patient sustained fatal injuries; and N407MJ's commercial pilot, flight paramedic, flight nurse, and patient sustained fatal injuries. N407GA was operated by Air Methods Corp., Englewood, Colorado, and registered to Flagstaff Medical Center, Flagstaff, Arizona. N407MJ was operated by Classic Helicopter Services, Page, Arizona, and registered to M&J Leisure, L.L.C., Ogden, Utah. Visual meteorological conditions prevailed, and company flight plans were filed for each of the Title 14 Code of Federal Regulations Part 135 air medical flights. N407GA's flight departed the Flagstaff Pulliam Airport (FLG), Flagstaff, at 1544, and N407MJ's flight departed the Grand Canyon National Park Service South Rim helibase, Tusayan, Arizona, at 1517. At 1516, the pilot of N407GA, call sign Angel 1, contacted Guardian Air dispatch at FLG and reported that they were departing Winslow, Arizona, with four people on board; the pilot, the two flight nurses and the patient. The pilot stated that his estimated time en route was 25 minutes and he was either going to land at FLG or proceed directly to the Flagstaff Medical Center (FMC) helipad. The pilot was not sure if he would be at the proper weight to land with enough power margin to execute an out of ground effect hover on the rooftop helipad. At 1519, the Guardian Air dispatch transportation coordinator contacted FMC and reported that Angel 1 was inbound to the helipad in approximately 23 minutes. At 1519, the pilot of N407MJ, call sign Lifeguard 2, contacted their communications center and reported that they had departed the south rim of the Grand Canyon and were en route to FMC with an estimated time en route of 32 minutes, and four people on board; the pilot, the flight nurse, the flight paramedic, and the patient. About a minute later, the pilot of Angel 1 called Guardian Air dispatch and reported that they were going to "drop one" at FLG before proceeding to land at Flagstaff Medical Center. At 1523, the dispatcher on duty at Classic Helicopter Service contacted Guardian Air dispatch and reported that Lifeguard 2 was en route to FMC and would be arriving from the north. The dispatcher also reported that it would be a "cold drop," and the emergency department at the hospital had already been notified. The Guardian Air dispatch transportation coordinator then informed the Classic dispatcher that Angel 1 was also en route and would be landing at Flagstaff Medical Center in 20 minutes. At the end of that call, the Guardian Air dispatch transportation coordinator called FMC and stated that Lifeguard 2 would also be landing at the hospital in "about twenty-eight minutes...and they know about mine coming in." The person who answered the phone in the emergency department responded, "all right." The transport coordinator then contacted the pilot of Angel 1 and informed him that Lifeguard 2 would also be landing at Flagstaff Medical Center in approximately 28 minutes. The pilot responded, "Roger will be looking for 'em thanks." At 1532, the pilot of Lifeguard 2 contacted the Classic Helicopter Service communication center, provided a position report and said that they were 15 minutes from landing at FMC. The dispatcher on duty responded, "comm center copies all sir...I'll talk to you on the ground in fifteen minutes, 1532." This was the last recorded communication with the pilot of N407MJ. Also at 1532, the pilot of Angel 1 contacted Guardian Air dispatch and reported that they were 10 minutes from landing at FLG. At 1544, the pilot of Angel 1 contacted Guardian Air dispatch and stated, "control Angel 1 if you haven't figured it out we've uh landed at the...airport departed and we're about two minutes out of the hospital." The transportation coordinator responded and copied the transmission. This was the last recorded communication with the pilot of N407GA. There were no recorded communications between the pilots of the two helicopters. A review of the recorded transmissions made between both medical crews and the hospital revealed that both of the medical crews contacted the emergency department at FMC and provided medical reports on their respective patients. At the time Angel 1 contacted the hospital, they provided an estimated time of arrival in 15 minutes. The Classic Helicopter Services medical crew reported an estimated time of arrival of 18 minutes. The hospital staff that received the phone calls from both aircraft did not provide any information about the other helicopter that was also en route to the Flagstaff Medical Center helipad. Several people witnessed the collision of the helicopters as they approached the hospital helipad and reported seeing both helicopters descending into wooded terrain about 1/4 mile from the heliport. There was a small fire noted rising from the hilly terrain, followed by a loud explosion shortly after the collision. A surveillance camera, mounted on a parking garage at the hospital, captured the collision on digital video. The video depicted one helicopter approaching from north and one helicopter approaching from the south, and shows both aircraft descending after the collision. The video was sent to the NTSB Vehicle Recorders laboratory, Washington, DC, for further examination. The accident site was located in a partially wooded, rocky mesa, approximately 1/4 mile east of the FMC helipad at an elevation of 7,060 feet mean sea level. N407GA's main wreckage was located on the top of the mesa in a rocky, grass terrain; and N407MJ's main wreckage was located in wooden terrain. The main wreckages of both helicopters came to rest approximately 300 feet apart from each other. The debris area, approximately 1/4 mile in diameter, contained fragmented sections of main rotor blades, plexiglass, and fiberglass. N407GA was partially consumed by post-impact fire and N407MJ did not have a post-impact fire. N407GA experienced a secondary post-impact explosion approximately 3 minutes after the accident. Three first responders sustained minor injuries during the explosion. At the time of the accident, the weather was reported as partly cloudy and winds were light and variable. *********************************************************************************************************************************** HISTORICAL SUMMARY: **UPDATE** During a visit to the crash site in April 2009, I located an intact media card from a digital camera. The photographic contents of the card appear to be the property of an a victim involved in the collision. The card has been returned. More to follow later.
