Apollo 15 used the first automotive vehicle on the moon.
The lunar module was named "Falcon" after the mascot of the Air Force Academy by the all-Air-Force crew of Apollo 15.
Scott was a colonel on his third spaceflight. Worden was a major and Irwin was a lieutenant colonel; it was the first spaceflight for both.
