I was pretty much just asking so I could answer the question myself. But that is a good point about Flight 93 being the only one they were certain of right away. But...

Another poster raised this point and I was wondering if you could shed some light on it. If a pilot switches the transponder on a plane, can it still be determined what plane it is? Or does the code on the ground have to match the one on the plane in order for the flight number and other info com up? If the information disappears, what is the procedure to reacquire it? How long might it take?

Thanks,
