Cliff said today that as a general premise, 'everyone knew that something had happened during the 8:10-8:20 period' because of a sudden increase in communications, especially between 305 and the company.
Another suspicion I had concerning a lot of cross talk with the company and less with artcc allowing gaps in the radio transcripts..
V23 was discussed i believe with the tower and TRACON doesn't seem to be a part of this flight and would be the one's who would of noted the route taken.
Wouldnt Cliff have been party to those discussions or have heard them ?
Cliff is adamant that the PI and NWA Transcripts leave out vital communications that occurred with 305, especially during the 8:10-20 period. Cliff did not use the word "redactions" but when he got started on this part of our conversation I thought I was about to hear something straight out of R99's narrative - then Cliff switched to these comm gaps being due to 'transcribers being overwhelmed, or selective', or he said: "literally not knowing what to do with all of those communications" so sticking to a kind of script, for the intended user! Cliff's characterization surprised me. Ive never heard anyone offer that explanation before!
Finding EU's post here today ... it sounds like EU and I got our nickel's worth today from Mr. Ammerman. Cliff is a great gentleman.
Let me add some comments related to several posts. Most of this information has been discussed before but some memories need to be refreshed.
While on the ground in Seattle, the airliner talked to the tower on the tower's ground control frequency. It was cleared to take off on this ground control frequency and told to contact Seattle on a certain frequency. When it called Seattle ATC, the answering controller was apparently surprised and had to ask them who they were and where they were. That took a couple of minutes to get things straightened out. This means that the airliner bypassed any TRACON (or tower and departure controller) controllers who were usually responsible for getting departing traffic into the ATC system.
Also while on the ground in Seattle, the airliner crew apparently was in communication on a radio link with the NWA ground personnel there. This means that NWA apparently had its own private ground frequency in Seattle. This was not part of the FAA system and would not be recorded or appear in the FAA radio transcripts.
The FAA tower frequencies and the Seattle ATC frequencies would be recorded on tape automatically. Those tapes should still exist since they were part of an aircraft "incident". Some human would then have to listen to those tapes and prepare a typed transcript of those conversations. As previously discussed on my attempts to get those transcripts released, it is the FBI that prevents the FAA from releasing those tapes. Three interventions by my US Representative and senior FBI managers were not able to get them released. So it may take an intervention with the FBI Director and/or Supreme Court if we are ever able to get those complete and unredacted transcripts.
After take off, the airliner crew communicated with NWA personnel in Minneapolis and Seattle over the ARINC system by a voice patch as well as the usual teletype messages. The voice patch was in real time and a few minutes later a "formatted" version of the same information would come through on the ARINC teletype system. The air traffic controllers would not have access to that information.
A few years ago, Fred Poynter and his group at the WSHM were given access to the teletype version of those communications. Fred's group made a study of them and determined that significant deletions had been made in those teletype messages. That is, entire messages had been deleted.
Thanks to Cliff Ammerman for the information. Does he know if Gerald H. Osterkamp is still alive? If so, can Osterkamp be contacted. He was the Chief of the Seattle ATC facility at the time of the hijacking.
I have still have some questions about the direct to Eugene flight path. Hopefully, more information will be forthcoming.
Kermit! Oh, Kermit!!! You may need to have your medications adjusted. ADDENDUM: And based on his last post above, Georger may need to do the same thing.
