8:47 At almost the same time American 11 crashed into the North Tower, United 175's transponder code changed several times. The changes were not noticed for several minutes as the controller tried to locate American 11.

Thanks. That might indicate that the hijack code was attempted to be entered. If that was the case then efforts were being made, they just failed.

That is also a possibility. But, who knows for sure? It could've went either way.
The Rapid Response Team (RRT) on Aircraft Security recently made recommendations for changes to aircraft design and operation that would help meet the demand for increased onboard security. An FAA-published report states that these modifications should include a method to ensure continuous transmission of a hijack signal, even if the flight deck selected code or function is turned off. Three suggested modifications that can be accomplished quickly are:
- Ability to set and lock in the hijacking code so the hijacker cannot disable it
- A panic button that initiates the hijacking code in an emergency situation
- An independent transponder that cannot be disabled by the hijacker
How it Works:
The Transponder lock installs behind the transponder control panel using existing wiring. No new wiring is required. When a pilot channels code 7500 using the existing control panel, the Transponder lock switches on and continuously transmits code 7500 until a company unique unlock code is channeled on the control panel and the aircraft is on the ground. Activation of the lock is indicated by a short (3 second) activation of the display test function on the control panel. Power interruptions do not defeat the lock. After the lock is engaged, the control panel ATCRBS output is ignored, precluding the transponder from entering standby or channeling another code. All TCAS mode selections continue to operate normally from the controller panel after the lock is engaged.
Optionally, an external PANIC switch may provide a direct trigger for the Transponder Lock. An AUX power input provides for switching the transponder to a backup power source, if the lock is enabled and primary power is lost. These optional features require the addition of two wires at the control panel.

In order to be credible all aspects of the official story must be addressed with a rational argument.

Headsets are not like in the movies with big round coverings. Headsets are tiny plastic ear pieces that are positioned just inside the ear and allow the pilot to hear not only ATC transmissions but everything else going on in the cockpit.

and, er...Badly trained in what? I mean, I know I disagree with their interpretation of Islam (which is kinda ironic, me being an infidel and all), but all those videos we've seen recovered from abandoned Al Qaida camps tend to suggest they were VERY well trained terrorists...

Plus, prior to Septeber 11, 2001, it might not have been plicy to hand over your Boeing, but how many jetliner hijackings had ended in ALL of the hostages dying?
Prior to September 11, 2001 smart money would have said "accede to hostage demands, fly to airport of their choice, sit tight and wait for SAS/GSG9/CIGN/Delta/Royal Netherlands Marines/Israeli Paras or other force who in recent decades have accomplished spectacularly successful hostage rescues."
Therefore, if a hijacker enters the cockpit holding a razor-sharp blade to the throat of a stewardess and demands the pilots leave their seats, it is no stretch of the imagination to accept that the pilots stood up and left their seats in the expectation that within a few days the cavalry would come to their rescue and they could all go home.

And for a short and in no way comprehensive list of hijackings that involved no deaths, I give you...
en.wikipedia.org...
John Lear a page or two back gives a diagram of the transponders and shows where the handset is located for talking to the passengers
after all, they managed to turn all four transponders off as a first act, apprantly!!
How can anyone claim an element of suprise when there has been no evidence that a cockpit door would have been able to be breached with a single kick? thats an assumption, and not liklely.

Do not forget that the pilots of flight 93 were attempting to confirm the messages they received when the hijackers stormed the cockpit.
