There are some things we have learned about UFOs over the last 70 years. One, is that they tend to be attracted to natural disasters, such as earthquakes, hurricanes, tornadoes and volcanic activity. Another, is that they have a particular interest toward nuclear weapons, facilities, and vessels. A third, is that they are often witnessed and reported either at airports or from aircraft. There have been many reports of near misses of a commercial aircraft encountering a UFO and we would venture to guess that military aircraft have also experienced many close calls.
