From one of my old columns. I'm not permitted to link to it directly, but here's the germane part:
Q: I have heard that pilots often see strange things in the sky, i.e. UFOs, but through tacit agreement will not openly discuss these sightings out of fear of embarrassment possible career suicide. True or false?
I have to laugh at the notion of there being a tacit agreement among pilots over anything, let alone UFO sightings. And although plenty of things in aviation are tantamount to "career suicide," withholding information about UFOs isn't one of them. For the record, I have never met a pilot who claims to have had a UFO sighting, and the topic is one that almost never comes up -- even during those long dark flights across the ocean.
