The computer would have been tracking it and had symbology assigned before the IFF was turned off. It would have continued to track by radar long after it was turned off. The only planes without IFF transponders are small private planes as you must have one to enter Class B airspace. Thus the only radar only returns travelling over 350 knots would be the airliner that had its transponder turned off.

However you are missing the point. The pilot said "If you listened to her carefully only an experienced pilot probably would have known that what she was saying was scripted,” but any student pilot would know what he is saying is false. It is required for the FAA written test to know something as basic as only altitude is encoded in Mode C of the transponder. For him to be wrong about so basic a thing lends doubt to him being a pilot at all.

OK seen the clip of wtc 7 collapsing i admit it does LOOK like a controlled demolition but if it is where are the explosions, i mean you can hear it collapse but no explosions, now your not going to tell me they've invented silent explosives are you.

I have a question, I'm just wondering about something. Is it really a good idea to put up the "Freedom Tower" in the place where the towers fell?? Isn't it just asking for the terrorists to attack all over again in the same spot??

This question kind of haunted me for a while now.

If we let terrorists cow us into submission, they win. You can't live your life in fear of what statistically is a very small threat. I think they should put up the biggest building in the world right there, as a big F-you to al Qaeda.
