"On July 4, 1986, 21-year-old Marine Lance Corporal, Howard Foote Jr., an aviation mechanic at El Toro, took an A4 Skyhawk on an unauthorized 90 minute joyride over southern California. Foote, an accomplished glider pilot, was despondent after recently learning that due a medical condition he would never be able to fly in the Marines".
According to subsequent news reports, LCpl Foote was not court-martialed but got an Other-Than-Honorable discharge as his punishment.
Guy I was stationed with at El Toro was tuned down for OCS due to some medical condition. Pissed him off, so he made the case that if he was no fit to be an officer, than not fit to me a Marine, and got out early on a medical.
