A giant fireball has consumed the World Trade Center complex.
United Flight 175, a fully-fueled Boeing 767, has struck the building deliberately.
Parts of the engine flew out the east side of the building and have landed six blocks away.
The tower physically shifted at least five feet.
Hundreds of people must be dead - and hundreds of millions watched their deaths on live TV.
This is not an accident.
Windows have been shattered across the North and South Towers of the World Trade Center by the blast a few minutes ago, and workers in the South Tower report feeling physical heat from hundreds of feet away. There is even smoke in the South Tower.
Nevertheless, public address announcements are ordering workers not to evacuate and return to their desks, as the fire only concerns the North Tower.
Radio and television communications across New York City have been severely hindered because the television and radio antenna on the North Tower has been rendered inoperable by the fire.
Amateur radio enthusiasts are now aiding with communication.
