POINT is....the entire notion of "remote control" as perpetuated/proposed by this thread's OP is nonsense.
It is a non-starter.
Done.
LaBTop :
Thus, it seems not so far fetched to suppose a remote control system to have been implemented, to stay on the safe side.
weedwhacker:
This claim is demonstrably wrong, and it is shown to be wrong in the NTSB history of the DFDR recorders' information. The controls IN THE COCKPIT were physically manipulated, after the take-overs. (We have only the AAL 77 and UAL 93 data that survived, but the inference can be applied to the other two).
I'll respond to your query, and will forgo any more irrelevant discussions about UAL 93 anymore, in THIS thread...since nothing brought forward, of late, has to do with "remote control"...in fact, if anything, the posts merely refute it, and reinforce the fact of the hijackers' being at the controls.

The time discrepancy regarding UAL 93 has been THOROUGHLY explained, and here on ATS threads. Several times.
I invite you to research.
Give me one link. I gave you a hundred.

Fudging the Timeline
There are several independent lines of evidence that establish that Flight 93 crashed at 10:06 in Shanksville, PA. These include the following:
* Seismic signals recorded by seismic observatories at Soldier's Delight, MD, and Millersville, PA, which pegged the impact time at 10:06:05, with an error margin of 5 seconds.
* A report from Cleveland Air Traffic Control that they had lost radar contact with Flight 93 at 10:06. (4)
* Reports by witnesses on the ground of the plane flying low and erratically around 10:05. (5)
* Various press reports that put the time at 10:06. (6;7;8)
* Radar records released by the FAA. The Post-Gazette noted, two days after the attack:
The Federal Aviation Administration said yesterday it turned over to the FBI a radar record of United Airlines Flight 93's route.
The data traced the Boeing 757-200 from its takeoff from Newark, N.J., to its violent end at 10:06 a.m., just outside Shanksville, about 80 miles southeast of Pittsburgh. 9
Despite these extensive bodies of credible evidence establishing Flight 93's impact time at 10:06 AM, NORAD and the 9/11 Commission asserted that impact was at 10:03. NORAD provides no evidence to back up its claim, but the Commission provides a long footnote to justify its use of 10:03.
United flight 93 departed Newark, NJ at 8:42 AM.
It flew 1 hour and 21 minutes.
The NTSB flight Profile times were based on the FDR, FAA radar data and radar data from the USAF RADES.
The Cockpit Voice Recorder CVR began providing sounds from the cockpit at approximately 9:32 Am.
The time of impact was 10:03:11 AM.
With the attacks unfolding, air traffic officials began issuing warnings through the Aircraft Communication Addressing and Reporting System (ACARS). Ed Ballinger, the United flight dispatcher, began sending text cockpit warnings to United Airlines flights at 09:19, after he became aware of the second World Trade Center impact by Flight 175.[19] As Ballinger was responsible for multiple flights, he did not send the message to Flight 93 until 09:23. Ballinger received a routine ACARS message from Flight 93 at 09:21.[19] At 09:22, after learning of the events at the World Trade Center, LeRoy Homer's wife, Melody Homer, had an ACARS message sent to her husband in the cockpit asking if he was okay.[27] At 09:24, Flight 93 received Ballinger's ACARS warning: "Beware any cockpit intrusion—two a/c [aircraft] hit World Trade Center".[28] At 09:26, the pilot sent an ACARS message back: "Ed, confirm latest mssg plz -- Jason".[28] At 09:27:25, the flight crew responded to routine radio traffic from air traffic controllers. This was the last communication made by the flight crew before the hijacking.[29]

911 Commission Footnote : ---- the impact time established by the very accurate combination of FDR, CVR, ATC, radar, and impact site data sets. These data sets constrain United 93's impact time to within 1 second, are airplane- and crash-site specific, and are based on time codes automatically recorded in the ATC audiotapes for the FAA centers and correlated with each data set in a process internationally accepted within the aviation accident investigation community.
All of the sources that the Report cites to support its claim of a crash time of 10:03 are apparently unavailable for public inspection, including Kim's 2004 paper, for which one will search in vain on the web. The " FDR, CVR, ATC, radar, and impact site data sets" cited by the Report all remain unavailable to the public. This contrasts with Kim and Baum's 2002 paper, which documents its case for the 10:06 crash time.
Early press reports consistently pegged the crash time at 10:06 or later. Only NORAD asserted that Flight 93 had crashed at 10:03. (Ref. 1, 2, 3, 4, 5.)
Weedwhacker, here are several agencies reporting an identical time-line for flight 93, based on ACARS messages send, several Radar reports, FAA reports, FAA witness reports and FBI reports.
In fact, the term is common enough for this 777 related website to use it in its title on the home page (The T7-Family)
WHAT "missing three minutes"??
The CVR and FDR stopped at exactly the same time, as I've pointed out, they both receive onboard time info from the Captain's clock, which is set by the pilots, and we can't assume it was EXACT. This ties in with the false assertion, mentioned in other threads, about the airborne time per ATC tapes, and their more accurate timelines.
reply to post by glitchinthematrix.
Interesting link to the timeline by Paul Thompson. As usual, eyewitness accounts conflict, and should be taken with a grain of salt....
However, I can clear this part up rather easily:
The 911 Timeline meticulously put together by Paul Thompson states that the official NORAD time of the Flight 93 crash in Shanksville, PA was at 10:03 AM.
There IS a three-minute discrepancy, and here is why.
From the seismic records, and also the FAA ATC radar, the actual time when radar contact was lost was ~10:06 EDT.
The Recorders (both CVR- Cockpit Voice Recorder - and FDR - Flight Data Recorder) stopped at time index 10:03 EDT (or, more correctly, 14:03 UTC).
Absent the equipment for GPS updating, which was not installed on UAL 93, the Recorders both get their time reference from the ADC (Air Data Computer) which, in turn, receives its time from the Captain's clock. The clock is set manually, by the crew. It can be somewhat laborious, at times (and frustrating, much like setting a VCR clock can be). Also, it may have been set by the maintenance personnel (mechanics) when they first prepped the airplane that morning. Either way, it was a few minutes off. Sometimes, that happens.
If we're going to fly an extended over-water route, then accurate times are more important (and just about all have GPS nowadays, anyway, so it is accurate automatically). The Captain's clock does not report outside the airplane; for that there is what's called the ACARS. It automatically reports the Out, Off, On and In times (among other things) for Flight Following requirements, per FAA regulations.
Once again, as I have repeatedly informed you....(and Skadi reminded you) the entire 'discrepancy' amounted to a total of THREE minutes!!! AND, it is easily explained by the fact that the time reference ONBOARD the airplane (which was the only time reference that the CVR and DVR had to go by) was totally dependent on the setting of the Captain's clock. At that time, the onboard clocks (for that equipment at United Airlines) did NOT receive any updates from ground-based sources.
The ATC time reference was, of course, the actual time --- based on NIST standards from Ft. Collins, Colorado. THERE is the three minutes' difference!!! You have been told this, countless times. I will let others, here, judge you accordingly for continuing to attempt to USE this already busted "information".
"Pilots for Truth" don't bother to investigate any deeper, they merely JUMP at any chance that they think looks like some sort of 'flaw'...hence their total lack of credibility. IF THEY HAD stopped, for a moment, to consider this other explanation, then they wouldn't have such fools of themselves. BUT...their 'mission' really is all about the $$$....not the "truth" of 9/11.....
And people who fall for their baloney, garbage, crapola? They should take a moment to seriously re-examine the source.....
Nowadays, more and more airplanes have GPS installed, and THAT does automatically update the Captain's clock...but, pre-GPS? It was set manually. The other unit onboard (ACARS) is automated, and uplinks the exact time, in sync with the 'standards' form Ft. Collins. It sends the flight-following stats ('OFF' and 'ON' times) and the 'OUT' and 'IN' for airline on-time reporting (and crew pay!!).
But, the ACARS doesn't tie in to the Captain's clock, nor the FDR and CVR.
Captain's clock actually serves the Air Data Computer (talking the B-757/767 here), which then supplies time reference for other items. (Except, again...the ACARS).
weedwhacker : Now, you've added some ATC transcripts, but the ones you found are LACKING times of transmission. THOSE times would co-incide with the overall 'global' standard time references.
-snipped some text-
You also included takeoff times, and such....BUT the CVR didn't record that far back...see if there are DFDR info from the entire flight, from push-back at the gate, to impact...THAT would be a sound basis for comparison. IF you find it, I suspect the time discrepancy, by comparing to ATC time reference, will be obvious.
I'll try a more prosaic example, scenario:
A car crashes in an intersection, and the entire event is caught on camera, with accurate time. The driver is killed, and the impact causes his wristwatch to stop. The Coroner can use the stopped watch as his reference for moment of death, or the camera time that recorded the event.
Do you see? WHICH is likely to be most accurate, to the second?
