[Source: United States Army]Helicopter crews with an Army aviation unit based near the Pentagon are initially unable to launch after returning from weapons training, because, they are told, they are “locked down until further notice.” (Exempt 11/14/2001 pdf file) The 12th Aviation Battalion is stationed at Davison Army Airfield, which is at Fort Belvoir, 12 miles south of the Pentagon. It is the Military District of Washington’s aviation support unit, and includes three helicopter companies that fly UH-1 “Huey” and UH-60 Black Hawk helicopters. (Military District of Washington 8/2000) But at the time of the attacks on the World Trade Center, an unspecified number of the battalion’s members were away at the shooting range at Fort AP Hill, for their annual weapons training (see 8:46 a.m.-9:37 a.m. September 11, 2001). They only set out on the one and a half to two hours drive back to base after the Pentagon was hit. One of the battalion’s helicopter pilots, who says the Pentagon is “basically one of our missions,” will later recall that after arriving back at Davison Airfield, his company commander “pretty much had us all get together, and he broke us down into aviation crews… and then he briefed us on what to expect.” The battalion’s helicopters are put “online,” meaning “we preflight our aircraft, got ready, and we went ahead and took everything out.” But, the pilot will say: “then basically we were locked down until further notice. That’s what we were told. And at that point, aviation got hit the hardest, so nobody was flying anywhere unless we had specific permission.… It was a waiting game.” The first helicopter to take off from Davison Airfield transports some engineers to the Pentagon, though the time it launches at is unstated. The 12th Aviation Battalion helicopters will subsequently be involved with supporting Operation Noble Eagle, the new homeland defense mission after 9/11. (Exempt 11/14/2001 pdf file)
