9/11 Flight Patterns

This has been checked on Snopes and Hoax Busters. It appears to be legit, since it was not listed as a hoax on either site.

Flights of September 11, 2001. Drastic course changes. Especially interesting how the two jets that hit the World Trade Center crossed patterns.

[and for--what, two hours?--not one jet was scrambled from Andrews AFB]
