Launched 10:15 local time. Launch failure. Carried pressure, density, ionosphere, sky brightness experiments for Air Research and Development Command.

TF-1 was the first V-2 launched by an all US Army team that was taking over from the General Electric crew as GE's contract to assemble, test and launch the missiles was coming to a close. It was the 'Final Exam' for this new team to prove were capable of handling the program from then on. Since no experiments were to be on board it was decided to shoot for an altitude record, and various modifications were made to this end. TF-1 was launched 12:00 local time. and reached 213.9 km.

AF flight 1. Launch aborted, but X-1D suffered low-order explosion during pressurization for fuel jettison. Plane jettisoned from B-50. X-1D exploded on impact with desert. Everest managed to get into B-50 bomb bay before drop. References: 49 , 97 .

Launched 00:33 local time. Reached 78.2 km. Carried composition, pressure, magnetic field, solar radiation; cosmic radiation (National Institute of Health); sky brightness (Air Research and Development Command) experiments for Naval Research Lab. V-2 number TF-2 was flown as contractor vehicle 59.

Responsibility for the design and manufacture of the reaction controls for the Apollo command module was shifted from The Marquardt Corporation to the Rocketdyne Division of NAA, with NASA concurrence. References: 16 .

The length of the Apollo service module was increased from 11 feet 8 inches to 12 feet 11 inches to provide space for additional fuel. References: 16 .

NASA informed four firms that had completed design studies on the Apollo experiment pallet that there would be no hardware development and fabrication of the pallet. The four firms had been selected in November 1965 to make four-month studies of a pallet to carry experiments in the spacecraft SM during the Apollo manned lunar landings. The firms were Lockheed Missiles and Space Co., Sunnyvale, Calif.; The Martin Co., Denver, Colo.; McDonnell Aircraft Corp., St. Louis, Mo.; and Northrop Space Laboratories, Hawthorne, Calif.

Communications was lost with the spacecraft on August 22, 1993 as it was preparing to go into orbit around Mars, and no significant scientific data was returned. Later investigation indicated this was due to a propulsion system explosion caused by propellants leaking past faulty valves.
