I have posted before about taking photos from airliners of passing jets and using Flightradar24 and the wifi connection to try and get a shot. On this trip I had two good opportunities that I knew about. The first was a 757 operated by FedEx. I could see it coming using the app. It was apparently not going to be a close pass but it was going to be within range. I saw the jet show up and shot a sequence of it as it came by. The shots were okay given the idea of shooting through windows. A better chance came with an American 737. It was going to be really close to our flight path. Actually, it was really close. Unfortunately, it came right under us. I saw it flash by but I only got shots of engine nacelles and wings of our own jet. Oh so close!
