Dallas-Fort Worth (DFW) - 5pm airliner departure push
Pensacola Regional (PNS) - 5pm airliner departure push
Any questions? ;-)
Incidentally, that DFW shot was taken on my return trip home from Oklahoma City in Summer 2007. That was the last time I've flown on an airliner.
Of course, I am just talking only about airliners. The Pensacola shot doesn't show the two naval air stations within 15 miles loaded with hundreds of navy jets, props, and helos who make that 5pm departure and arrival push far more interesting!
