These records are not public. There are enthusiasts that track such things. What sounds like the accident you speak of is mentioned here:
crashed 13.09.1978 into the sea. During a night catapult launch, the a/c launch bar was placed on the lip of the shuttle, vice in the throat. Prior to launch the pilot selected mil. power and indicated to the cat officer that he was ready to go. As the shuttle was released the a/c, in the kneeled position, started down the cat track, whereupon the launch bar slipped off hte lip of the shuttle. Zone 5 afterburner (Z5) was selected at or shortly after shuttle release, realizing that the a/c would not attain flying speed, the crew ejected. With approx. 1,000 lbs removed from the a/c nose and due to the nose strut extending, the a/c pitched up as it left the deck. The a/c, in Z5 went into a loop type maneuver, peaking at an altitude of approx. 3,000 ft, then descended and crashed 200 - 300 yards off the port bow! Both crewmen were successfully recovered. Post accident investigation revealed (plat tape analysis) that the flight deck crewman responsible for ensuring that the tow bar was properly placed in the throat of the shuttle was improperly positioned so that he could not see the tow bar. Medical records showed that the crewman was nearly blind under night flight deck conditions and that he had not had an eye examination for several years!!!
