Before he passed away in the early 2000s, Peter Jennings did a really good documentary on UFOs called Seeing is Believing. It's one of the most comprehensive and least weird/edge/conspiracy documentaries for its time and it's still interesting today. He goes into how pilots saw many unidentified objects going back several decades. I think there are a lot of people who acknowledged these sightings do exist, but there has to be some explanation; some natural phenomenon we haven't identified and discovered.
