Robert, when the hell are you going to read my book? The answers to these questions are all addressed there in detail. But in the spirit of Forum Decorum I will tell you this:
1. Container was a Pioneer.
2. Chute was a Steinthaul, 26' conical canopy, white, rip-stop nylon.
3. I have no knowledge of the pilot chute.
4. Pix of the harness were posted a page or two back, see post by Georger.
This information comes from Norman Hayden, who owned the two back chutes that went to Flight 305. Norman said he sent two identical back chutes. He received one back and the other went out the door of the 727, presumably with DBC. The "other chute" from Hayden was given to the WSHM in 2013, and is now part of their collection. It was on public display at their COOPER exhibit.
I inspected Hayden's chute at his shop in Renton in 2012. I was accompanied by Bruce Thun, a jump ship pilot and parachutist for many years. His father, John, was the founder and owner of the noted Thun Field in Pierce County, WA for fifty years. This chute is the one I photographed for the Mountain News. Lots o' pix there, for a more detailed understanding of this parachute. Bruce was very helpful in assisting me in understanding the nuances of the Steinthaul and Pioneer rig.
From this, I have surmised that everything else put forward about the chutes is total canard - especially everything that Cossey and Carr said. Carr clearly has not read the FBI documents on the parachutes, and he refuses to educate himself even though I have tried to straighten him out on this subject.
As for Cossey, he was a total bullshit artist. Besides his inconsistent DBC statements to the FBI, the media, and private investigators, and his unsolved murder, there is much more to investigate, such as his departure from his teaching gig in Woodinville.
Cossey's family are not helping us understand ol' Coss. The son is totally adversarial. He tried to have me arrested during the police investigation of his father's home when I approached him to discuss some of these issues. Later, he refused to answer phone calls, letters, and emails. In addition, Debbie Cossey has refused all contact after her ex-husband's death. Further, the Major Case squad of the Kings County Sheriff's Office is mum on the homicide. Friends of Coss who have talked to me say that they have initiated contact with the KCSO and shared information about Coss' serious gambling addiction and his association with shady characters. However, these friends have told me that the cops have not acted upon any of their information, and they feel a cover-up is under way.
