I'm glad Fly is diving into this issue. He has sent me a ton o' stuff over the past few days. Some of the tidbits that have impressed me are as follows:
1. The FBI talked to someone about the parachutes early on, perhaps the night of the skyjacking - late though, like 3 am. Was it Cossey? Unclear. What is clear is that Cossey was interviewed by the feds on Friday, 11. 26. 71, and he gave a parachute description that closely matches what the FBI received on 11. 24.71 in the wee hours. But the description that ended up in the Parachute Summary Report, as revealed by Geoffrey Gray in 2011, was in the FBI's hands within hours of the skyjacking.
2. RMB finally offers some valuable information from his two-part interview with Hayden, in which he reveals that Hayden told him he bought the two back chutes in 1968 from a surplus store that got them packed for him by Cossey at Issaquah Sky Sports prior to delivery to Hayden. What RMB has written jibes with what Hayden told me, so I figure it's true. Hayden couldn't remember where or when he bought the chutes when I talked with him in 2014, but he figured it was a surplus supply store, and he had no memory of getting them packed nor of ever meeting with Cossey.
