Re: If they scrambled so fast, I wonder why they didn't catch up to the plane till it reached Memphis

The Learjet is capable of 500 mph and was headed away from Tyndall Air Force base when the jets were scrambled.

Here is the speed of the F-15s and F-16s on 9/11/01

9:02:54: UA175 impacts the South Tower of the WTC between the 78th and 84th floors. NORAD says the F-15's from Otis are still 71 miles away. This means their average flight speed was only 23.9% of their top speed in trying to intercept UA 175. Otis is 153 miles from WTC - F-15's have a top speed of 1875 MPH. Minus 71 miles from 153 miles = 82 miles covered in 11 minutes from 8:52 to 9:03 -
60 minutes divided by 11 minutes = 5.45 x 82 miles = 447.3 MPH divided by 1875 MPH = 23.9%.

9:49: It takes the F-16's from Langley 19 minutes to reach Washington. This means their average flight speed was only 27.4% of their top speed in trying to protect our nations capital. Langley is 130 miles from the Pentagon - F-16's have a top speed of 1500 MPH - 60 minutes divided by 19 minutes = 3.16 x 130 miles = 410.5 MPH divided by 1500 MPH = 27.4%.
