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.

- 1951 Sep 14 - Nation: USSR.
The aircraft went out of control and Ziese bailed out of the aircraft. The destruction of this rocketplane resulted in further tests being abandoned.
- 1951 September - Nation: USA.
The uses of rendezvous techniques in space were discussed in a paper read to the Second International Congress on Astronautics in London, England. The problems involved in refueling in space might be simplified considerably if astronauts could maneuver freely, perhaps using a gas-jet pistol and a lifeline. The construction of a space station might then be possible. Mechanical linkage of objects in space was described as the most difficult task of all. While computing the position of an object in orbit might be comparatively easy, linking up with the object without damage by impact would require human intelligence to anticipate error in the attitude of approach.
