Another quote from the new documents:
"Anderson stated that approximately 5 to 10 minutes after the last contact with subject at 8:05 pm, they heard and felt an oscillation of the aircraft and commented that the hijacker could have departed causing the unusual vibration since there had been no change in flight parameters or any other external force which would account for this sudden vibration. They telephoned the company representative ( __________ in ___________) shortly thereafter and stated that the ‘oscillation’ which could have been the hijacker’s departure, would have occurred between 8:05 pm and their call to the company 5 or ten minutes later, the exact time being recorded in the company log. Anderson stated that they had not reached Portland proper but were definitely in the suburbs or immediate vicinity thereof."
This would also coincide with what Barb told us about the jump that night. She stated she went a bit down on the stairs to look for the lights of Portland to start her timing to the jump site, then waited at the top out of the wind to do her timing and wait for the search light from Aurora airport to hit the plane at a 45 degree angle. Note that with flying in those wind conditions and with that configuration of the airplane, the ride would be quite bumpy. The pilots would have been more in tune to a slight oscillation in the time directly after the door opened and could easily have missed a second slight oscillation. Or perhaps the second oscillation occurred when there was more buffeting of the plane.
As we read through these documents we are more convinced than ever that Barb was D B. The phrases mentioned, the offering of the money, the point where Tina says he shows a sense of humor, all sound exactly like the Barb we knew.
