I have always maintained that DB Cooper removed some of the packets of twenties from the bank bag before he secured it and jumped because it was too full.
Importantly, I have also stated that I believe that the excess packets of twenties that DBC removed were wrapped into the dummy reserve and that this explains how some of the packets of twenties got separated from the bank bag and ended up being left behind on Tena Bar.
The 302’s for Tina Mucklow tell a story and I think prove that DBC did, in fact, remove some of the packets of twenties from the bank bag.
One of Tina’s 302’s states that by the time she brought the final parachute onto the jet that DBC had already cut shroud lines from one of the reserves and that he had used these lines to wrap around the neck of the bank bag, wrap around the bank bag from top to bottom and to create a type of handle. Simply put, the bank bag was already tied closed with the money inside.
However, a 302 from Tina also states that DBC complained that he would have to wrap the money into one of the parachute canopies, and that she actually saw him doing this.
What makes this interesting is that the 302 says she saw him attempting to wrap the money into the canopy as they were seated and getting reading to take off from SeaTac.
How is this possible? How can Tina see DBC wrapping packets of cash in a parachute canopy if the money bag is already tied with the money inside? Also, it’s been reported in her 302 that DBC offered her a packet of twenties, yet the money was already secured inside the bank bag. Again, how is this possible?
The only rational explanation is that DBC had removed some of the packets before he secured the bank bag and it was the excess packets of twenties that he removed that she saw and is referring to.
I think it is entirely likely that Tina did not understand exactly what DBC was doing and had done. More to the point, she may not have realized that DBC had pulled some of the packets out of the bank bag and that what she witnessed was him attempting to secure that portion of the ransom in the canopy.
Additionally, seeing the pink canopy lying on the floor, Tina may have associated the act of securing the excess packets with the pink parachute even though in reality DBC used the missing dummy reserve with the white canopy. Perhaps, DBC did initially try to use the pink canopy but later—after Tina was up front—opted to use the less bulky dummy reserve instead. Regardless, the end result is still the same.
There is no way to rationalize the bank bag being secured with the money inside by the time Tina brings the final parachute onboard with the fact that she saw him working with at least some of the money after that point. The only explanation is that DBC removed some of the packets of twenties from the bank bag before he secured it. And, that these excess packets were wrapped into the dummy reserve. And, that this is how at least three packets of twenties got separated from the rest of the ransom in the money bag and left behind on Tena Bar.
