- two piston tests were conducted
- first conducted at about 9in Hg (approx. 30,000 ft)
- second conducted at 3in Hg (approx. 80,000ft)
- observed slow and premature extension of piston rod with depressurization
- suggests piston is not pressure-sealed
- from the expanding air sealed into the bottom of the piston
- second test will be conducted to determine if this premature extension will break the shear pinspistons will be unable to deploy above 30k ft and thus co2 ejection systems will be used for Medusa
