Memorandum presenting an investigation of reaction controls that command velocity and attitude that compares them to the controls that command acceleration. Proportional acceleration reaction controls were found to be satisfactory over a much wide range of control effectiveness than were the on-off acceleration controls. The velocity and attitude controls were found to be superior to either of the acceleration controls

"The Bell X-2 supersonic research airplane is equipped with a skid main landing gear and a nose wheel. Pending completion of the rocket engine, glide flights are being performed to determine low-speed handling qualities of the airplane and the landing characteristics with the skid-type landing gear. The present paper presents data obtained during the approach and landing of the X-2 airplane on its first flight" (p. 1)

Memorandum describing a flight program consisting of exploratory flights to determine the Mach number and altitude capabilities of the Bell X-1A research airplane. On two flights of X-1 airplane, one reaching a Mach number of about 2.44, the other a geometric altitude of about 90,000 feet, lateral stability difficulties were encountered which resulted in uncontrolled rolling motions of the airplane at Mach numbers near 2.0
