Section C tests would run through October 10, 1941. The series of twenty-four static and flight tests (P13-P36) was made with rockets of large fuel capacity, with the rocket motor, pumps, and turbines previously developed. These rockets averaged nearly 22 ft in length, and were 18 in, in diameter. They weighed empty from 190 to 240 lb. The liquid-oxygen load averaged about 140 lb, the gasoline 112 lb, making 'quarter-ton' loaded rockets. References: 482 .
Launched 15:34 local time. Reached 145.6 km. Carried biological (Harvard), solar radiation (Naval Research Lab), composition (Signal Corps Engineering Lab, University of Michigan) experiments for General Electric.
Launched 08:03 local time. Reached 124.2 km. Carried winds, composition, temperature; cosmic radiation (APL, John Hopkins); and solar radiation (Naval Research Lab) experiments for Signal Corps Engineering Lab, University of Michigan.
Inertial guidance system for Navaho X-10 missile tested in first flight at Downey, Calif. References: 17 .
Successfully fired from AMR at 2031 hours EST to a pre-calculated range of 664.8 nm. Nose cone impacted 0.9 nm over and 1.0 nm left of the target. This was the first medium range flight for a tactical prototype. References: 439 .
Nike-Asp sounding rocket fired from NASA Wallops Station emitted sodium vapor at 50-mile altitude to 150 miles, revealing powerful windshear effects. References: 17 .
This was a flight test of the Ranger spacecraft system designed for future lunar and interplanetary missions. The spacecraft was launched into a low earth parking orbit, but an inoperative roll gyro prevented Agena restart resulting in Ranger 2 being stranded in low earth orbit. The orbit decayed and the spacecraft reentered Earth's atmosphere on 20 November 1961. References: 1 , 2 , 5 , 6 , 16 , 278 , 296 .
As requested by Robert C. Seamans, Jr., at the monthly program meeting during October, Associate Administrator for Manned Space Flight George E. Mueller summarized the agency's present plans for including the DOD's astronaut maneuvering unit 'back pack' aboard AAP flights.
