Didn't TWA 800 go down around dusk? If I remember correctly the whole scene was viewed from Fire Island. I also remember that the aircraft was sent to an empty hanger in Calverton, Long Island, NY. Sort of remember that the dive team were Navy personnel. Somewhere in the recesses of my gray matter is that a reporter was arrested for having fabric tested for explosive residue. Jim Kalstrom was in charge of the investigation.
I think you are correct on all counts.
