What to do while waiting on the apron of the airport? Why, take photos out the window, of course.
This was on a flight back from Norfolk to Baltimore. At first, there didn't seem to be any "there", there, but after a while, I got to playing with the angles formed by the wing and nacelle, the luggage loader and the cart behind it.
By the way, we sat there for about two hours; the flight crew spotted a potential wing flap problem as we were almost ready to taxi to the runway. Southwest called in a mechanic, but the problem wasn't fixable on the spot, so we rolled back to the gate and deplaned. With a new part beign flown in, they were estimating that the plane would be fixed and depart in about three hours. We decided to punt and rented a car - it was a pleasant afternoon and an easy ride back.
