On April 21, 1958, a Douglas DC-7 operated by United Air Lines collided with a USAF F-100F military training jet at 21,000 feet. The collision occurred ten miles south of Las Vegas, Nevada and killed 49 persons including the two pilots of the military jet.

After the large pieces of wreckage were removed from the impact site of the airliner, officials from United Air Lines wasted little time by burying the remaining debris from the curious public.

For nearly four decades the main impact site of the DC-7 had been untouched. It's location forgotten and unknown.

During 1995, after an extensive search, the DC-7 impact site was re-located. The site however was far from safe as commercial developers had already begun surveying the land for future construction. It was decided to try and save as much historical material as we could from destruction. Using conventional archaeological mapping and excavation techniques, the DC-7 main impact site yielded an amazing collection of artifacts that were recovered, documented, and preserved.

In addition to the DC-7 main impact site, material was also recovered and documented from the DC-7 engine impact site, F-100F impact site, and the collision debris field located in between the two main impact locations.

Today, the DC-7 main impact site has been graded and buried over for the development of a commercial business. The debris field is slowly being developed over as housing and commercial expansion continues to the south of Las Vegas.
