The EA-7L went into the hills above Santa Barbara .An investigation followed, and  there was never an answer to what actually caused the ejection. Both the pilot and the nav said they were flying along north of Santa Barbara one minute, and were rocketing through the air the next. Talk about a surprise!!! An intense search of the hills failed to turn up the ejection seats, so  the answer as to what happened is still lying in the hills above Santa Barbara. Some things are simply meant to be mysteries
