If they looked at the FDR several times it tells me that something is possibly confusing them. what would be on the FDR for them to extend the search area's. would this be pressure spikes, or the fact of them not knowing exactly where the plane was during these readings on the FDR?
The document above suggest a distance of over 25 miles of possible jump times....that's north of the Lewis river all the way down to the Columbia...
It is a mystery to me why they would try to reconstruct the flight path from the data on the FDR. Much more accurate data would be in the Seattle ATC radio transcripts.
Take a look at the Oakland ATC and Reno tower radio transcripts to see what should be in the Seattle ATC radio transcripts, but had been deleted.
So the pressure spike time would be about the only useful thing available from the FDR.
From the context of the document, it looks more like they were using the FDR to try to time the jump, they were not trying to reconstruct the flight path since they already had it from the radar. What's interesting is that they couldn't get a precise time for the jump from the FDR; in the document they are relying on the cockpit testimony to shorten the window of the jump.
If the aircraft track presented on the so-called "FBI map" is for the hijacked airliner, then why didn't the controllers make some effort to get the airliner back on the airway centerline and to keep it from wandering all over the place while in the Portland area?
It is to be noted that neither the Seattle ATC, Oakland ATC or Reno tower, nor the airliner crew, indicated any problems with the airliner flying a given track. The airliner crew indicated that they did have problems descending at certain vertical speeds when making turns, but this was not related to the track of the airplane in level flight.
What do those red "X" marks on the west, southwest, and south sides of Portland, which are also shown on the "FBI map", mean to you?
