The mushroom cloud from a GBU-43/B, also known as the Massive Ordnance Air Blast (MOAB), can be seen rising in this Air Force video still image after it was launched successfully from a MC-130E Combat Talon I aircraft on Nov. 21, 2003. The 21,700-pound bomb was dropped from 20,000 feet to reach its target on one of Eglin's test ranges. Upon detonation, it created a plume over the Florida Panhandle that rose more than 10,000 feet and can be seen from 40 miles away. (AP Photo/HO) Released.
