So... when i was deeply concentrating on the movie (with the window closed to eliminate distractions, the flight attendant poked me in the back to tell me i could see a second plane out the window. Can you see it?
Maybe you can see it here?
And here is a shot to give you a sense of 'scale' (so you can see the wing of the plane i was on in the shot)
We seemed to be flying parallel to each other... not exactly 'circling', but in a bit of a holding pattern.
And then we landed in parallel. You can't quite see the plane in this shot, but we landed on parallel runways at the same time. Well... that was a first for me...
