Forty-five years later, during recovery of wreckage from TWA800 / 17Jul96,   on about 1Sep96 during storm surge associated with Hurricane Edouard,   a very worn 4' fragment of aircraft wreckage was pulled from beach sand near E. Hampton L.I.     Fragment proved to be a B707 STA 1440 Aft Pressure Bulkhead.   After long examination, the unknown aircraft part was ID'd by TWA-MCI Engn'r Gene Livingston,  by using faded p/n stamped on component,  with positive identification returned from Boeing’s  IPC-database.    Suspect this Bulkhead, and numerous heavy steel Spar-"Tuning-Fork" sections collected at the Calverton Hanger (during TWA800 investigation),  came from the 28-Jan'61 AA B707 -- and the worn fracture-faces seem to confirm the age of those fragments.  Over decades that  heavy fragment from that  B707 Aft Pressure Bulkhead had migrated with the current, southwesterly,  along the Long Island coast,  at a rate averaging about a mile per year.

  Souls-on-Board (Sob) = 6,  all killed.    Departed NY Int'l A/P  @ 1100 est,  pilot training,  clear wx,  at about 1220 pm witnesses observed aircraft in steep dive w/ left wing low, impacted offshore, into ocean​.

About 15% of wreckage was recovered, including all four engines:

   concluded that  #1 Engine had separated inflight,   no malfunction of engines, nor inflight explosion, nor structural failure.   Wing Flaps were extended to about 30 degree position at impact;   FDR not recovered (only unused pieces of foil found).   Suspected that last training maneuver might have been the "canyon approach"  (which utilizes Flaps 30).

   P.C. =  loss of control   for an undetermined reason.
