Just watched the film. Thanks for posting, OP.
I had no idea till now that there was/is a conspiracy that Arrow 206 escaped destruction, and in the act broke all speed and altitude records, performed a 2G turn at 50,000' at supersonic cruise without losing altitude, flew to the edge of space, flamed out, stalled out, lost all control and altitude only to regain control moments before crashing, all with an illicit engineer passenger aboard, then had enough remaining fuel to fly far away to destinations unknown and remain in hiding for 60 years. Simply amazing. I believe it.
As a matter of fact I've never felt so certain that it was Arrow 206 that shot down TWA800. I'm betting flight 800 had onboard the family of the Canadian prime minister that terminated the Arrow program. It was a revenge killing.
