OVER NEVADA -- A B-52H Stratofortress drops a load of M-117 750-pound bombs during a training run here. During Desert Storm, B-52s delivered 40 percent of all the weapons dropped by coalition forces. The first Gulf War saw the longest strike mission in the history of aerial warfare when B-52s took off from Barksdale Air Force Base, La., launched conventional air-launched cruise missiles and returned to Barksdale -- a 35-hour, non-stop combat mission.
