Yesterday evening there was a program on TLC that talked about UFO sightings by pilots, and also interviewed a bunch of pilots. They had some good air-to-air shots of a Delta 767-300, a Lufthansa A310, & a lufthansa 320. It will probably be repeated again on TLC sometime soon as all their programs are (so you might want to watch out for it just in case you are interested).
So anyway, just out of curiosity, what is the general opinion of forum members on UFO? Any of you pilots out there seen one?
