As we try to digest the recent reports from TLC, I'd like to bring up another matter. I spent most of the day with my older brother who retired from Portland Boeing in 2001. I asked him when he started at Boeing and he said 1966. He said it was Electronic Speciallties at the time he was hired. I recalled that also but asked him why Boeing bought them out in 1974 from Iron Fireman who have been manufacturing parts for Boeing for many years. He said both Iron Fireman and Electronic Specialty were names both used within the plant. He didn't really know about the ownership details. What is relevant is that Iron Fireman has been making part for Boeing for many years. Perhaps I missed it on this site but IF there is suspicion that COOP might have been a Boeing employee, has anyone done any investigation into Iron Fireman/Electronic Specialty ? I jokingly mentioned it to my brother that perhaps he might have been working with good old COOP. He just smiled !
Kermit,
Do you know what type of parts Iron Fireman/Electronic Specialty made for Boeing?
And do yo know where they were located in Portland? Were they on the PIA property or have free access to it?
ADDENDUM:
Let me add a bit more information here. I have long speculated that Cooper was a US Government employee (or former employee) and that includes military service and working for a government subcontractor.
Cooper did know that the rear stairs on the 727 could be lowered in flight but did not know how to lower them himself, even after Tina gave him specific instructions on how to do so. This suggests to me that he was not directly involved in the production of the airline aircraft. However, it is highly likely that the modified 727s that were used in SEA had a different control panel and a more powerful motor to insure that the stairs could be closed in flight, plus other modifications. This would require different electronics for the modified aft stairs.
Cooper's parachute experience appears to have been quite limited or maybe even non-existent. He apparently knew how to put on an emergency parachute and, presumably, how to use it. Cooper could have been taught this on the ground in less than five minutes. There is nothing at all to suggest that Cooper had made a parachute jump previously.
Cooper's knowledge of the flap setting, airspeed, altitude, gear position, etc., that he specified for the flight to Reno could have been gathered from talking to others. Or maybe he was even involved in the flight testing of the modified aft stairs that Boeing did.
So I suggest further checking into this "Electronic Specialty" company and exactly what they produced for Boeing.
