Astronaut -Candidate (ASCAN) Guion S. Bluford and Aviation Safety Officer Charles F. Hayes got a unique perspective of their environment during a zero- gravity flight. They are aboard a KC-135 Aircraft, which flies a special pattern repeatedly to afford a series of 30-seconds-of-weightlessness sessions. Astronauts Bluford and Hayes are being assisted by C. P. Stanley of the Photography Branch of the Photographic Technology Division (PTD) at Johnson Space Center (JSC). Some medical studies and a Motion Sickness Experiment were conducted on this particular flight. Astronaut Bluford is one of 20 Scientist/ASCAN's who began training at JSC, 07/1978. 1. Dr. Jeffrey A.
