Crystal 7

 1985-F02

---

CRYSTAL 7 was launched in Aug 1985 but failed to reach orbit when one of the engines on core stage 1 failed to start properly and shut down prematurely. It would have entered the 1300LTDN east plane orbit.

Investigation put the blame on propellant leaks in the engines, but Wayne Eleazar commented that some involved in the investigation suspected the real root problem might have been an SRM burnthrough with a side plume of flame causing the stage 1 damage.
