R99, EU, Shutter, Georger, and anyone who has really focused on the flight path: Refresh me if you can. Do we know an exact timestamp and location at any point on the flight path, even the exact takeoff time? I thought there were a few points where we know for sure where the plane was and at an exact time, but as it got closer to the jump time of 8:12, 8:13 etc, that it got a little questionable. Didn't Shutter program a few exact spots/times in the flight simulation? R99, is this all that redacted info you've been searching for? Thanks.
The time stamps in the Seattle ATC radio transcripts and the Oakland ATC radio transcripts are Greenwich Mean Time and accurate to the second. Captain Scott said the takeoff time from SEATAC was 7:36 PM PST and the airliner was talking to the Seattle ATC Center by 7:37:11 PM PST so Scott's statement is accurate.
At 9:45 PM PST, the airliner is handed off to the Oakland ATC Center and the Seattle end of the conversation is included in the Oakland ATC radio transcripts. The Oakland ATC radio transcripts include the telephone communications between Oakland ATC and Seattle ATC controllers. The Seattle ATC controller tells the Oakland ATC controller at 9:45 PM PST that the airliner is one mile south of the Fort Jones VORTAC in Northern California. The Oakland ATC controller then locates the airliner and the handoff is made.
The above times and locations are accurate. But with a bit less accuracy, three more positions and times can be estimated for the airliner between SEATAC and just south of Portland. This involves comparing the times of transmissions over the ARINC radio patch and the time stamp of those transmissions over the ARINC teletype network.
The 19 deletions from the Seattle ATC radio transcripts would all be concerned with air traffic control matters and give such things as locations and times at those locations. The transmissions between the flight crew and the NWA offices in Seattle and Minneapolis would all be conducted over the ARINC radio patch and teletype network. Inputs from the FBI and others would be over the ARINC telephone patch.
Personnel at the WSHM had access to many of the ARINC teletype transmissions that were made from the airliner during the hijacking. They concluded that a number of these transmissions had also been deleted. So we have more deletions here also.
Those 19 deletions in the Seattle ATC radio transcripts, which are actually in the public domain, are what I tried to obtain by three FOIA request through the FBI/FAA and my US Congressman. None were successful.
