Okay, the biggest obvious reason it only aired once is due to the dialogue of the journalist. Listen to him explicitly say that there is NO evidence that a plane hit this building. He says there is no tail piece, wing pieces, etc. No sign whatsoever that a plane was even there.
Then, take a look at all those light poles. If a plane had flown through at the angle required to hit that building at the angle it was allegedly hit, it would have mowed those light poles down like tall grass.
What are your thoughts on this? Was it a plane? Or was it an inside job, committed by your Government to take away more of your freedoms ?
