Got an itch to play with Hansa-Brandenburgs...here's the result.
On Dec.11, 1917 a flight of three W-12s led by ObLtn. Friedrich Christiansen, was on the homeward leg of their patrol. Nearing the coast, the No.3 plane, the 'Tail-End Charley', spoted an Asta-Torres airship and dove to the attack. Christiansen and his other wingman turned back to join in, but by the time they arrived it was burning. Neither plane could add much to the process as the C27 was already going down. Being Flt. Leader, Christiansen claimed the kill, and it was confirmed. After the war, in subsequent statements, he acknowledged the role of his No.3, and some accounts credit each with half a kill.
EDIT: Here's the re-make. All planes now have pilots and gunners. The second picture is different because, for some reason, the file corrupted and everything, planes, lights, etc., were stacked at the same point in space: 0,0,0. So it had to be re-built.
