Do Airlines Track Their Planes By Gps Or Radar?, Flight 93 question Options

[woody]

Kevin Fenton has obtained a very interesting transcript from FAA HQ per FOIA:

http://www.historycommons.org/sourcedocume...ation031014.pdf

According to this document, United Airlines tracked Flight 93 over Hagerstown, Maryland, heading towards Washington.

According to the official story, Flight 93 was never there; but even the 9/11 Commission confirms that a radar blip, believed to be Flight 93, was tracked by ATC for several minutes after the Shanksville explosion.

The commission wants to tell us that controllers were only tracking the "projected flight path" of the plane. But this FAA document seems to belie them. "hack89" over at Democratic Underground claims that the airlines track their planes by GPS, which would constitute the final proof that this radar blip was no projection, but the REAL Flight 93. But is hack89 right?

hmmm... interesting.

I have seen many companies track their flights using a commercial/business version of Flight Explorer, which in turn uses FAA radar IIRC. Not sure what United uses. Best bet is to call/email them and ask and/or try to find a dispatcher who works/worked there.

As for the tracking on FAA radar after shanksville. From what i understand, radar goes into "coast" mode when a target is lost. Im sure google can turn up more on radar "coast mode".

Thanks for the post woody! Let us know how you make out...

Thanks woody,

"Hack89" might be correct regarding GPS today, but I'd bet a couple of paychecks that the majority of commercial transport aircraft did NOT have GPS navigation systems back in Sept. 2001. I'm likely more familiar with [military] GPS targeting systems than 95%+ of the people that you will meet on the street...

Yes, the "coast mode" explanation has been overtaken by Cheap Shot and John Farmer, they say that controllers were staring at the "Traffic Situation Display". But I'm just collecting independent evidence that this Flight 93 was no projection, but a real-world plane (this document for instance).

I'm going to publish this evidence soon, hoping to push this "projected flight path theory" into the realm of fantasy.

Woody,

I'm assuming that you are aware that the alleged FAA spreadsheet "data" released in [EDIT: mid September] 2008 has a "UAL93" landing at Reagan National DCA at 10:28 EDT...

EDIT: FAA has that "UAL93" as a "B752" [Boeing 757-200 from my research], and answering the topic title, airlines track aircraft using Mode 3A and Mode C SSR transponder "ping" info (which will soon be upgraded to Mode S IIRC).

I look forward to it woody! Please be sure to drop by and post a link when published.

......As I recall ( and the old brain that has been vibrated by turboprop and jet engines is slow), dispatch tracked a/c either by FAA radar data, ACARS (if they had it), or more basic data.....few a/c had gps receivers, much less transmitters......often, the FAA data was transmitted to the dispatch centers and overlayed over wx data....

Don't know if this will be of any direct or indirect help, thought it might at least be of interest.

Thanks a lot for the information, dmole, very helpful. I somehow missed your post, sorry for the late response.

As for the "UA 93 landed at Reagan Airport at 9:28" thing, I admit I'm skeptical, mainly because the 9:28 time was also the EAT (Expected Arrival Time) of UA93's data tag in the Flight Explorer animation. I'd like to have at least some kind of confirmation before I jump on this.

My post-Shanksville UA93 stuff has to wait, by the way. I just detected Steven Miller's account on the differing departure of Flight 175, something I was looking for for years. Most exciting.
