Well some aircraft designers get inspired by UFO sightings. Or if a UFO crashes they will rebulid it so yes.
Yes, one of the most famous supposed UFO crashes occurred in the 1940s. It was called the "Roswell incident."
Nome, Alaska seems to have been a hotbed of UFO activity. Crashes, sightings, craft found in ice, ect. Who would have known.
