Just wondering. this video says a 767-200 is not capable of more then 250/300 mph at 700ft. I think there wrong, because the airliner that hit the pentagon did with such force it destroyed most of the aircraft...It had to be moving over 500mph right?

The 767 has a take off speed of about 120kn, and cruises at a maximum speed of 470kn at 35,000'. (specs)
At ground level, due to the drag, load, its speed would be limited to around 250-300kn. (1kn = 1.18mph)

Impact at 300 mph is more than enough to send it deep into the building and obliterate something as massive as a 767. Remember too that the burning fuel is what did most of the damage. Also keep in mind that the number quoted is cruising speed. If it we *diving*, it could have been going much faster because gravity would be contributing to it's acceleration.

Both Planes: Boeing 767-222, Weight empty: 176,650 lbs, wt full 181,650lbs
North Tower (Tower 1) - Hit at 8:46 AM; Floors 93-99; 466 MPH; collapse after 102 minutes
South Tower (Tower 2) - Hit at 9:02 AM; Floors 77-85; Speed 590 MPH collapse after 56 minutes.
Pentagon Impact speed was computed at 521 MPH
Sorry my original info was wrong. The above is from Wikipedia & appears to be reliable.
