maybe he asked for two chest parachutes and two backpack parachutes,
assuming he was going to get 4 independent rigs....

SEADD ARE IN CTC WITH LOCAL BANK AND
ARRANGING FOR THE MONEY ND WILL HAVE
THE TWO CHEST PACKS SOON ALREADY HAVE
THE TWO BACK PACKS
Maybe the ground team thought they were being smart by giving him chest plus back rigs. Or maybe they were just stalling for time.
So this whole thing about the training reserve may be bogus. Cooper might
have just tossed it.
There's the whole military/civilian chute backstory that's not in the transcripts. Maybe they talked to the military and then talked to Cooper again, but Cooper rejected the military chutes (as has been reported). I think it was just a verbal rejection if so. In any case, maybe the ground team started this whole 4 parachute thing...chest vs back....?
You are correct about there being conflicting stories regarding the D.B. Cooper affair. I don't think that anyone really knows the complete story about Cooper's plans, communications, or actions.
However confusing things might seem regarding the chutes, one would have to reasonably conclude that Cooper jumped off the plane wearing one of the two backpacks which Earl Cossey had packed and delivered to the police car that evening. Whether or not he used one of the chest chutes, or whether or not one was a dummy is trumped by the fact that he went out the door with what was likely a working back pack chute.
I believe that the communication quoted above regarding the Bank negotiations for money and of them HAVING two backpacks and trying to obtain two chest chutes, most likely was referring to the two Military Parachutes that had been located first. My interpretation of the remark about the chest chutes is that it was IN REPLY to a previous request for them. And that it was likely a request from Cooper relayed by the pilot.
I doubt that the FBI would have been looking for Chest Chutes because they thought it might be a nice safety measure or because they had nothing better to do.
There is testimony by the FBI officer in charge regarding Cooper's rejection of the first two chutes (sight unseen, as they were still airborne) because they were Military Chutes. It is only speculation as to WHY he rejected them, but it could have been for a couple of reasons: First, he may have only had previous MILITARY jump experience using static line cords and wanted a chute with a ripcord handle that he could pull. And Second, he may have wanted them to have to get something very quickly so that they did not have time to sabatoge the chute to cause it to not open.
Cooper never stated WHY he wanted the two chutes/sets of chutes, but he was ASKED by the stewardess if he intended to take a hostage with him, and he replied "Maybe". It is unknown whether or not that information was relayed to the FBI during the course of the evening's events, but would be a very likely assumption for them to make. The point being; If the FBI thought that Cooper planned to jump with a hostage, they would be less likely to sabatoge the chutes.
