I believe that is a photo of one of 2 B24's Adolf galland shot down with R4m Rockets, in in his book one of his last few air engagements he came from high and above and launched all 24 R4m rockets and hit a PAIR of b24's in one pass, I'll go back and check the dates and time of when this happen, but I believe that image is of one of the B24's going down (not entirely sure will check)
Yeah he hit 2 B24's in one pass, he was chased away by mustangs shortly after, but I do recall one of the P51 pilots later on stating he watched the "262 dive on a formation and let loose some kind of rockets, watching in horror as 2 blew up on impact"
French ace Pierre Clostermann notes in his book The Big Show that in March 1945, six R4M-armed Me 262s flying out of the Oberammergau flight test center and led by Luftwaffe General Gordon Gollob claimed to have shot down fourteen B-17s in a mission.
