To them a fighter jet might as well be a Cessna. Maybe not. Even when it all started, a few cases were alledgedly air combat: https://en.wikipedia.org/wiki/Mantell_UFO_incident https://en.wikipedia.org/wiki/Mantell_UFO_incident Other incidents crashes, like Roswell. Obviously I cannot vouch for any of those :-) just wanted to point that air fighters at the time were much less sophisticated than today. Maybe people that travels between stars are not so interested in bringing state-of-the-art war machines with them. The technology to maneuver a drone or vehicle at incredible speed or angles might still be vulnerable to bullets or missiles.
