One of the lesser known radical design concepts for an advanced fighter aircraft: An Argus pulse-jet powered Me 328, seen here mounted on a Do 217 K V3 during a test flight. Date unknown.

Me 328 jet fighter

A Ju 87 'Stuka' of 2./St.G 2 returning from a sortie in central or southern Russia. Note the flak damage near  the cockpit which most probably injured or killed the rear gunner, who by this time must have collapsed since he cannot be seen in his usual position. Date unknown.

Damaged Stuka

The three barrels of the SG 116 'Zellendusche' installed in a Fw 190 of Eprobungskommando 25. This experimental weapon consisted of a recoilless, single-shot, 30mm device and was to be fired upwards as the fighter passed under a bomber. It was to be activated automatically using a photo-electric cell. Trials were carried out by Ekdo. 25 in 1944 but proved to be largely unsuccessful.
