(AMC), known as the "Eagle Wing", and the AMC-gained 512th Airlift Wing (512 AW) of the Air Force Reserve Command (AFRC), referred to as the "Liberty Wing". It was previously the only base to solely operate the massive C-5 Galaxy and now operates both that aircraft plus the C-17 Globemaster III. The 436 AW has two active flying squadrons (the 3rd Airlift Squadron, which now operates the C-17, and 9th Airlift Squadron), and the 512 AW has two AFRC flying squadrons (the 326th Airlift Squadron and the 709th Airlift Squadron). Dover AFB is also the home for the largest military mortuary in the Department of Defense, and has been used for processing military personnel killed in both war and peacetime; the remains of those killed overseas are traditionally brought to Dover AFB before being transferred to family. The Charles C. Carson Center for Mortuary Affairs has also been used to identify remains of civilians in certain exceptional circumstances: in 1978 for the victims of the Jonestown mass murder/suicide, in 1986 for identifying the remains of the crew of the Space Shuttle Challenger, and in 2003 for the crew of the Space Shuttle Columbia. It was also a major site for identifying the remains of military personnel killed in the 9/11 attacks. During the night of October 28, 2009, before making a decision on the committal of further troops to Afghanistan, President Barack Obama visited the base to receive the bodies of several American soldiers killed in Afghanistan. Two sections of the 436th Aerial Port Squadron warehouse collapsed on February 18, 2003, as a result of a record snow storm. No one was injured in the collapse that caused more than an estimated $1 million in damages. The damage covered two of the six cargo processing bays in the facility. Dover AFB is also home to the Air Mobility Command Museum. Air Show Dover Air Force Base holds an annual air show, with the most recent occurring in May 2022. The show includes static displays of military aircraft and equipment, and flight demonstrations of the United States Air Force Thunderbirds or United States Navy Blue Angels demonstration teams.
