Langley's Pilotless Aircraft Research Division conducted, at Wallops Island, the first full-scale test simulating a pad-abort situation. A full weight and size spacecraft was used. For the first 50 feet the flight was essentially straight, indicating the successful functioning of the abort rocket. Thereafter, the spacecraft pitched through several turns and impacted a short distance from the shore. The malfunction was traced to the loss of a graphite insert from one of the three abort rocket nozzles, which caused a misalignment of thrust. References: 483 .

Pioneer V, launched as a probe of the space between Earth and Venus, began to provide invaluable information on solar flare effects, particle energies and distributions and magnetic phenomena. Pioneer V continued to transmit such data until on June 26, 1960, when at a distance of 22.5 million miles from Earth, it established a new communications record. References: 483 .

MSC directed North American to incorporate the capability for storing a kit-type mapping and survey system into the basic Block II configuration. The actual hardware, which would be installed in the equipment bay of certain SMs (designated by MSC), would weigh up to 680 kg (1,500 lbs). References: 16 .

The additional direct cost to the Apollo research and development program from the January 27, 1967, Apollo 204 fire was estimated at $410 million, principally for spacecraft modifications, NASA Associate Administrator for Manned Space Flight George E. Mueller testified in congressional hearings. The accident delayed the first manned flight of the spacecraft by about 18 months. "During this period, however, there occurred a successful unmanned test of the Lunar Module and two unmanned tests of the Saturn V vehicle." References: 16 .
