While flying to Philadelphia on 9-11, I was mesmerized by the cloud formations and started taking pictures (since the window was clean enough on some areas). I noticed a different streak in the sky and looked closer. I realized it was another jet plane close to ours. As soon as I took this photo, the jet made a quick turn right above us. It's not often I see a plane that close-up, I had to tell my seatmate (who was busy playing his computer game :-).
@darylo@tuya@genesis_one@hjv YES, clean airplane windows! I actually had some amazing shots of Mount Rainier and cool cloud formations but chose this one since I'm not sure when I will get this opportunity again.
