The odds of anyone surviving a jump from 10,000+ feet in pitch black over a heavy forest at the cruising speed of a 727 is very slim. Even if he did manage to land without injury there is still the problem of navigating the NW woods to a rendezvous point. Even if we assume the plane was flying the exact course he instructed and he jumped at the exact time he planned he could easily be 20-30 miles off course and with no GPS a compass is not going to do a whole lot.
If I remember right the plane was flying through a storm at the time as well.
Then there is the fact that some of the money was found a few year ago which leads me to believe that D B Cooper died in the fall from the plane.
One would think he had military experience jumping?
Could he have pretended to jump and snuck off the plane later?
D.B. Cooper exited the Boeing 727 into a 500+ mph windstream and was instantly sucked ass-over-teakettle into his parachute and fell thousands of feet to his death. Simple.
So you’re saying there’s a chance?
