An escape crew capsule allows a pilot (or astronaut) to escape from their craft while it is subjected to extreme conditions such as high speed or altitude. The crewman remains encapsulated and protected until such time as the external environment is suitable for direct exposure or the capsule reaches the ground. ==Escape types== There are two ways to do this: * Ejecting individual crew capsules (one for each pilot/crew member) or "capsule ejection" * Ejecting the entire crew cabin, or "cabin ejection" Some examples of U.S. military aircraft that have escape crew capsules are:〔(B.F.Goodrich - ''HISTORY OF AIRCRAFT ESCAPE SYSTEM PROPULSION'' )〕 * The B-58 Hustler and XB-70 Valkyrie had individual encapsulated seats. A cabin ejection for the XB-70 Valkyrie was also tested. The B-58's capsule had a control stick, a bottle of oxygen, and a drogue chute. * The F-111 used cabin ejection where both side-by-side seats were in a single 3000 lb (1360 kg) capsule.〔(Ejection Site - ''F-111 Aardvark'' )〕 * Three of the four B-1A prototypes also used cabin ejection. They had a single capsule "roughly the size of a mini-van" 〔(Ejection Site - ''B-1A Lancer'' )〕 for all four crew members. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「escape crew capsule」の詳細全文を読む スポンサード リンク
