The following quote comes from the Public Affairs Office at Davis-Monthan Air Force Base:

“Davis-Monthan AFB and the Arizona Aerospace Foundation’s Pima Air & Space Museum (PASM) no longer offer tours of the 309th Aerospace Maintenance and Regeneration Group (AMARG), also known as “America’s National-Level Airpower Reservoir,” or the “Boneyard.” For nearly 23 years, PASM positively affected the experience of visitors from the local Tucson community, the United States, and from across the globe by providing public tours of AMARG, one of the base’s 34 mission partners.

The 309th AMARG serves as an active aircraft maintenance, storage, parts reclamation and regeneration facility that Department of Defense warfighters, government agencies and many allied nations rely upon. Evolving requirements and manpower limitations at both Davis-Monthan and PASM have resulted in the inability to continue the public tour program without an adverse impact to our respective missions.
