If unmanned aircraft are so good, why do we need pilots? Travel with R. Lee Ermey to Edwards AFB for a look at the latest in experimental planes. See how Scottish kids, afraid of the Bogey Man, gave rise to the pilot term for unidentified aircraft. Watch the first combat helicopter, the U.S. YR-4B, flown in WWII by Lt. Carter Harman in Burma. See how forward observers direct artillery fire, and join Ermey as he demonstrates the Fairbairn-Sykes commando knife on his favorite target--a watermelon!
