The U.S. Air Force confirmed on the 23rd that the two specially-reinforced E4-B Boeing 747s that were designed to withstand the impact of a nuclear explosion damaged a tornado a few days ago.
AFP quoted the United States Air Force spokesman Pat Ryder as saying that the aircraft was manufactured during the Cold War in the 1970s. It is envisaged that once the United States encounters a nuclear-weapons attack, the planes will also be able to survive intact and assume the role of an air command center.
On the 16th of this month, a tornado struck at the Air Force Base in Nebraska, and the two E4-B planes were severely damaged. In addition, seven RC-135 reconnaissance planes were slightly damaged and another plane needed to be inspected.
It is understood that the U.S. Air Force has a total of four reinforced E4-B aircraft. (Yang Shuyi) [Xinhua Newsletter]
