Addendum: I may have the climb instruction to TWA800 partially wrong. It was originally told to climb to 19,000 feet (FL190) but this was rescinded. When told to climb later on it may have been told to climb and report when passing 15,000 feet which could have been the trigger event for the anti-terrorism test to begin. My memory is not totally clear as to whether or not TWA800 was told the second time to go to an implied 19,000 or 15,000 feet. But the net effect was that it was not yet at 15,000 feet since the target vehicle was deployed early.

Imagine my surprise. Why not try the ATC Transcript?
