On June 18, 1986, a DHC-6-300 Twin Otter tour aircraft operated by Grand Canyon Airlines and a Bell 206 JetRanger III Helicopter operated by Helitech, Inc. collided over the southwestern slope of Mencius Temple in the Grand Canyon. All 25 persons aboard were killed.

After the NTSB's on-site investigation, wreckage from both aircraft were removed by salvage teams and stored on private land for several years. With permission from the land owner, I recovered the items pictured in this gallery as part of establishing an historical archive collection of this accident. The LostFlights wreckage recoveries occurred during the early 1990s and recent visits to the wreckage dump site in 2005-2008.
