NORTH NORTHWEST OF HEISSON, WASHINGTON. THESE COMPUTATIONS WERE ARRIVED AT BASED ON THE ALTITUDE, DIRECTION AND SPEED OF THE AIRCRAFT WHICH WAS THEN FLYING VECTOR BETWEEN SEATTLE AND PORTLAND WHEN A PRESSURE BUMP AND OSCELATION OF THE AIRCRAFT WAS NOTED BY THE CREW. TO THOSE FAMILIAR WITH THE AIRCRAFT, IT WOULD INDICATE THE REAR DOOR WAS OPENED, CAUSING THE PRESSURE TO DROP AND WOULD BE A VERY LIKELY TIME FOR UNSUB'S DEPARTURE FROM THE AIRCRAFT.

HIS NOTES INDICATE THAT AT MINNEAPOLIS TIME TWENTY ONE FORTY ONE A STEWARDESS WAS ORDERED TO THE COCKPIT BY THE HIJACKER. AT TWENTY ONE FORTY TWO THE HIJACKER ADVISED BY INTER-PHONE THAT HE WAS HAVING DIFFICULTY GETTING STEPS DOWN. AT TWENTY TWO ZERO FIVE THE COCKPIT WAS IN COMMUNICATION WITH THE HIJACKER, AND AT TWENTY TWO TEN THE PRESSURE BUMP AND OSCELATION OCCURRED. NO FURTHER COMMUNICATION WAS HAD WITH THE UNSUB SUBSEQUENT TO THIS TIME.
