Rocket was equipped with new parachute release operated by gyro; altitude 1500 ft; duration 20 sec; speed very high; landed 3000 ft from tower, softened ground for considerable distance. References: 482 .
Experience with the X-15 design indicated that many of the weight figures advanced by the Langley Aeronautical Laboratory for the drag or lift configurations of the reentry vehicle (later to become the Mercury spacecraft) were too low, according to Walter C. Williams, Chief of the NACA High-Speed Flight Station. Weights of auxiliary-power fuel, research instrumentation, and cockpit equipment as set by Langley were too low in terms of X-15 experience. Williams stated the total weight should be 2,300 pounds for the drag configuration and 2,500 pounds for the lifting configuration. References: 483 .
Successfully fired at 1459 hours EST from the AMR. The flight was successful in that all missions were accomplished. Impact was 461 meters over end 64 meters to the left of the predicted impact point, a radial miss distance of 466 meters. Missed aimpoint by 245 m. References: 439 .
Fired from AMR at 1850 hours EST. The primary mission of impacting the nose cone in a pre-calculated target (MILS Network) was successfully accomplished, The nose cone impacted in the 1,302 nm target area, 2.8 nm over, with no lateral deviations. Again, the vernier engine ran to cut-off rather than the commanded 14 seconds -- a near perfect flight. For the first rime, missile roll was controlled by a turbine exhaust nozzle designed to eliminate problems experienced on previous flights. References: 439 .
100-foot-diameter inflatable sphere successfully launched on third suborbital test to an altitude of 225 miles, from NASA Wallops Station, Va. Radio transmissions were reflected via the sphere from Holmdel, N.J., to Round Hill, Mass. References: 17 .
First mission of the KH-4 series. Much of film slightly out of focus.. Capsule recovered 4.1 days later. References: 1 , 2 , 5 , 6 .
Boilerplate (BP) 19 was drop tested at El Centro, Calif., simulating flight conditions and recovery of BP-12. A second BP-19 drop, on April 8, removed all constraints on the BP-12 configuration and earth landing system. Another aim, to obtain information on vehicle dynamics, was not accomplished because of the early firing of a backup drogue parachute. References: 16 .
