What we typically think of UFO sightings as ground to air. Someone on the ground sees something in the air, however, air to air sightings are quite frequent also. The three UFO videos released in 2017, which were recorded by naval aviators, were all air to air, and many pilots of all types have reported near misses. It is extremely rare however to have a pilot of a commercial jetliner tell the passengers to brace for impact with the UFO. The video is amazing and you can see it below.
