First Convair MX-774 (RTV-A-2) test rocket was successfully launched, first demonstrating use of gimballed engines and design features later incorporated in the Atlas ICBM. This was the first of three Convair-sponsored test flights. References: 17 .

Reached 1.5 km altitude.

The first 5-1 aircraft, controlled on its first glide flight by A K Pakhomov, was dropped from a Pe-8 bomber.

Photography research. Launched at 1441 local time. Reached 112.7 km. Two separate rockets fired from White Sands, one a V-2 which reached an altitude of 87 km, the other a Navy Aerobee which reached an altitude of 112.7 km, carried cameras which photographed the curvature of the earth.

Launched 11:03 local time. Reached 87.1 km. Carried cosmic radiation, photo, pressure, temperature experiments for Applied Physics Lab, John Hopkins University. Fired from White Sands simultaneous with a Navy Aerobee which reached an altitude of 110 km. Both carried cameras which photographed the curvature of the earth.
