His Distinguished Flying Cross with Valor Citation reads:

Captain George B. Lockhart distinguished himself by heroism while participating in aerial flight as a B-52 Copilot near Hanoi, North Vietnam, on 20 December 1972. On that date, while participating in one of the largest conventional bombing raids ever amassed in the recent history of aerial warfare, Captain Lockhart's aircraft received significant battle damage as the result of extremely heavy hostile fire. Captain Lockhart and his crew were targeted against massed supplies, communications equipment, and transportation lines in order to eliminate the aggressor's capacity to initiate an offensive, and despite receiving heavy battle damage and incurring grave personal danger, Captain Lockhart and his crew maintained their position within the strike force until the very last minute to avoid civilian casualties. The outstanding heroism and selfless devotion to duty displayed by Captain Lockhart reflect great credit upon himself and the United States Air Force.
