Thanks for the reply John.
Most of the questions that I have asked pertain to pre-9/11 procedures. If you would, I have a couple of more questions.
1. What is the procedure to change the transponder code?
The transponder is located either on the overhead panel or the center console. It consists of 4 moveable dials which show numbers one through seven. 2
round knobs (1, 2) dial change the first 2 numbers and last 2 numbers. The hijack code is 4 numbers.
If someone is trying to enter the cockpit by force one of the pilots reaches over and turns those dials to the hijack code. It should only take about
2 seconds, maybe three or four seconds depending on how far the digits set are from the hijack code. (The button on top of the first knob labeled
IDENT is pressed at the request of ATC. The button on top of the second knob labeled TEST is a test function.) Both of those knobs turn independently
of the IDENT and TEST buttons.
This is the transponder located on the center console, between the pilots, of the Lockheed L-1011.
2. When you say two seconds, is that under ideal conditions?
2 to 4 seconds assuming you aren't grappling with a hijacker.
3. Do you believe that you could do it in two seconds after someone had breached the cockpit?
There are too many variables to answer that question so it would depend.
If I was fighting for my life it might not be my first prioity to set the hijack code. But I have the airplane controls the rapid movement of which
would instantly disable a hijacker.
Someone once proposed that a trained killer could enter the cockpit and slit the throats of the captain and co-pilot before they knew what was
happening. Unlikely. But lets assume for the sake of the argument that that happened. There would be so much blood in the cockpit that it would be
physically impossible to take the seat belt off of of the crewmembers and drag them out of their seats and drag them into the cabin. (There is not
enough room between the back of the pilots seats and the cockpit door for 2 dead bodies.)
Remember that the pilots seat move electrically forward after the pilots are seated to put them in position to fly. It would be impossible to drag a
body, assuming you could unfasten the seat belt, out of his seat if you had just slit his throat. The pilots legs fit under the instrument panel and
extend forward to the rudder pedals. You would have to lift, boost, lift, boost lift, boost to get his legs from under the instrument panel.
My opinion is that there is no way that hijackers successfully disabled 8 pilots. There were too many options available to the pilots and in the case
of Flight 77 FDR there is not the slightest indication of any altercation whatsoever during that flight.
