Defending base last night, everything looked clear for a few so I was cruising under 5k and looking for low bogies trying bug out. I kept seeing the edges of a red icon on the deck, but I'd zoom down and lose it. Waited, and sure enough, when it broke over water, it started to climb. It was identified simply as "G-S", with a range count and the little Bishop symbol. Some of the other players later said "G-S" is a bomber gunner? There was no plane there. I followed it until I was within d200 and began shooting at it, right at the icon, and in a circle around it. There was no indication of hitting anything, and no indication it saw me or tried to evade.
I have film of it, but I have no way to host it. I can send it if needed.
