Study is made of problems associated with manned vehicles entering earth's atmosphere at speeds from 50,000 to 65,000 fps required for manned vehicles upon return to earth from planetary missions; use of entire corridor requires perfect on-board knowledge of entry angle, velocity, and altitude; study investigates reduction in usable corridor depth due to small errors in knowledge of these qualities; it is found that substantial portion of corridor near overshoot limit is unusable because of extreme sensitivity of trajectories to errors in entry flight-path angle.
