(I voluntary repost this picture posted by me in former times because the quality of the now photo is better of the previous and because some most complete information about the event). The photo show a detail of the same event remembered by the picture “Bisleys in action” (Other Forces): the strafing of a Luftwaffe’s Junkers Ju 52 forced down by three Bristol Bisley of No. 15 Squadron South African Air Force, Western Desert, 12 October 1942. Notice the cannon shells exploding around the tail while the fire erupting by the starboard engine and a member of the crew lying face down on the ground beneath the airplane (indicated by the arrow over the print proof). The event occurred when the SAAF’s Bisleys, escorted by four Bristol Beaufighter of No. 252 Squadron RAF, while returning from a strike on an enemy train, intercepted two Ju 52. The Beaufighters shot down a Ju 52 and damaged one of the escorting Messerschmitt Bf 110s, while the Bisleys forced down a second Ju 52 (the aircraft of the photo) and subsequently destroyed it. One of the Bisleys was shot down by return fire. Victor Sierra

The SG 500 Jagdfaust was an experimental airborne anti-bomber recoilless rifle designed for use in the Me 163 Komet rocket plane by the German Luftwaffe during World War II. The weapon featured a simple form of automated trigger in which an optical photocell detected the dark silhouette of an Allied bomber replacing bright blue sky and triggered the firing of the armed Jagdfaust guns.
The Komet was so fast that pilots found it difficult to fire enough cannon rounds to destroy a bomber in a single pass. The Jagdfaust was developed to address this problem. A 5 cm shell was mounted in a launch tube held in place by a pair of thin pins. Five such tubes were mounted vertically (to fire upward) in each wing root. The design was based on the Schräge Musik, the manually triggered upward-firing air-to-air cannon extensively deployed with the Luftwaffe night fighter squadrons.
The launch tubes were rifled for greater stability of the projectile in flight. The greater resistance of rifling also served to eliminate recoil forces of the weapon affecting the aircraft. When the weapon fired, the force of the launch would break the pins holding the tube in place and the heavy tube was accelerated in the direction opposite to that of the shell. The moving tube corrected for the effect of the launch forces on the airframe. Hence the name, "Fighter plane fist"; like the "Armour fist" or "Panzerfaust," it was a recoilless weapon based on the same Newtonian 'action equals reaction' principle.

The Jagdfaust used a 5 cm "Minengranate" shell, whose thin walls traded fragmentation for additional explosives; when detonated within an aircraft with sheet metal skin, the skin would be blown off to devastating effect.

The entire weapon was designed for economy. Because it was intended for short range use, the shell had an aerodynamically inefficient shape that could be easily forged or stamped. Its tolerances were loose, as its long-range accuracy was not an issue. Instead of a driving band, the shell flared at its base and was machined to engage the rifling. The launch tube was made of soft unalloyed steel since it would not need to keep its rifling over multiple firings. The shell used a simple type of fuse instead of the more complex and expensive AZ 39 Safety Fuse. It was probably shipped pre-assembled and ready to install.

The weapon system is credited with one kill, that of an Allied B-17 Flying Fortress. Though initial results were promising, the war ended before it could see extensive deployment.
Here we have a destroyed Me-163B Jagdfaust in Germany 1945.

Crew of a Dornier Do 24 seaplane of Luftwaffe’s 6. Seenotstaffel at Augusta, Syracuse, Sicily, 1942. According the source on the left of the shot is Oblt. Wölke Staffelkapitän der 6. Seenotstaffel, KIA on 13 November 1942. The 6. Seenotstaffel, a search-and-rescue unit, fuselage code K3+, was established in Augusta on March 1941 under the control of the Taormina’s Rescue Coordination Center and subordinated to Seenotzentrale (L) Sizilien from March 1941 to June 1942 and to Seenotbereichskommando X from June 1942 to 18 August 1944 when was disbanded. On August 1943 moved to Portofino and later, October 1943, to Venice. In this time employed also some Italian floatplanes Cant-Z-506 seized after the Italy’s surrender. Victor Sierra
