A B-1 Lancer flies over the Norma Brown building during the 75th Diamond Anniversary ceremony on Goodfellow Air Force Base, Texas, Jan. 26, 2016. The B-1 flew over after a Vultee BT-15 Valient flew over. Both were symbolic; the vintage BT-15 represented the planes that Goodfellow pilots trained on, and the B-1 represented the intelligence support training the base now provides.
