The video below contains an interview with air traffic controller Dave Bottaglia, who says he tracked Flight 175. Battiglia's account suggests that at about 9:00, UAL175 was in a powerdive of 10,000 feet per minute, which the controller says would be "unbelievable for the passengers in the back, to withstand that kind of force when they're descending."
Yet the official story is that Peter Hanson began a three-minute phone call at 9:00.
He never described being in a dive or having come out of a dive. There doesn't seem to be any way he could call during the dive described and it seems unlikely he could even call just after such a dive. If he could, it seems unlikely he would not mention it having just come out of a horrific dive.
Here's what he said:
"At 9:00, Lee Hanson received a second call from his son Peter:
'It's getting bad, Dad-A stewardess was stabbed-They seem to have knives and Mace-They said they have a bomb-It's getting very bad on the plane-Passengers are throwing up and getting sick-The plane is making jerky movements-I don't think the pilot is flying the plane-I think we are going down-I think they intend to go to Chicago or someplace and fly into a building-Don't worry, Dad- If it happens, it'll be very fast-My God, my God.'"
This tells me not that the call is faked, but that the UAL175 is not the plane tracked by the air traffic controller in the above video.
If so, we don't know where the plane was or at what altitude it was at when Hanson called his father. He seemed to think the plane was heading toward Chicago.
The calls could be real, and still inconsistent with the official story. These issues should be explored before claims that they are fake.
