The crew of US Park Police Aviation resources are frequently called to assist at significant and historical disasters and emergency incidents throughout the National Capital Region. These incidents include the September 11 attacks on the Pentagon, the D.C. sniper attacks throughout the region, the crashing of Air Florida Flight 90, and the Washington Navy Yard shooting in 2013. During the Congressional baseball shooting, the crews of U.S. Park Police Aviation responded with two helicopters and transported Congressman Steve Scalise and a U.S. Capitol Police Officer to the trauma center at MedStar Washington Hospital Center.
