World Trade Center

Another Boeing jet - this one a 757 owned by United Airlines - left Boston’s Logan Airport at 08:14 EDT as Flight 175, also bound for Los Angeles. Hijackers took control of the plane and, at 09:02:59 EDT, rammed it into the South Tower at about the 80th floor.

Just before the plane crash, Peter Hanson, one of the passengers, called his parents. He told them that hijackers had control of the plane and had stabbed one of the cabin crew. The official "9-ll Commission Report," in chapter 1, Section 1.1, quotes Peter's 9 a.m. message (scroll down 20%):

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.

Cameras, focused on the burning first tower, broadcast the second crash on live television. A BBC journalist, Steve Evans, had no clue that his viewers were watching the second crash as they listened to his report of the first one.

Some of the people trapped in the towers, above the crash sites, jumped from the buildings rather than wait for inevitable death. All 65 people on board Flight 175, including flight attendants and pilots, were killed.

What was it like to be in the South Tower as it was struck? Might there be another reason that people fell to their deaths from the burning buildings?
