Low temperature enhanced probability of blow-by. STS-51C experienced worst case temperature change in Florida history. STS-51E could exhibit same behavior.
Condition is acceptable.
STS-51E field joints are acceptable for flight. These conclusions were accepted and the flight was certified ready for launch. Arnie proposed that subscale lab tests be conducted which would provide us with assessment data. The resiliency testing was performed in March and showed that low temperature was a problem. The results indicated that the seals would lift off their sealing surfaces for several seconds at 75 degrees Fahrenheit and in excess of 10 minutes at 50 degrees Fahrenheit.
