October 1918 a German aircraft was destroyed on the ground by firing a Very light into the aircraft. The D.F.W. two-seater was first seen in the air; the first German aircraft since aerial fighting over Deraa on 16 and 17 September just prior to the beginning of the Battle of Sharon. The two-seater was forced to land and was destroyed after the German pilot and observer had moved to safety. In 1942, a German pilot mistakenly landed at the Pembrey Airfield in Wales. The duty pilot, Sgt. Jeffreys, did not have a conventional weapon, so he grabbed a Flare pistol and used it to capture the German pilot, Oberleutnant Armin Faber. In World War II, Germany manufactured grenades designed to be fired from adapted flare guns known as the Kampfpistole, or Sturmpistole in its final form. The weapon was designed to function as an anti-tank weapon but failed to perform to expectations due to the minuscule amount of TNT carried in the hollow charge projectiles. In the later stages of the Korean War, on November 2 of 1951, Lieutenant Edward Mastronardi and his 28-man platoon of the Royal Canadian Regiment were occupying a spur halfway between UN and Chinese lines known as the Song-gok. During the night, Chinese infantry launched several attacks against the spur. During the second attack, Mastronardi personally shot two Chinese soldiers with his Inglis Hi-Power pistol, and killed a third with his flare gun. Conversion kits Conversion kits are available intended to convert flare guns to accept conventional ammunition by use of barrel inserts. There are also 12 gauge inserts intended to allow use of rifle or pistol ammunition in conventional 12 gauge shotguns. Use of any of these devices in the Orion plastic 12 gauge flare gun is not recommended by the manufacturer and ATF tests have demonstrated that sometimes a single use results in a catastrophic failure. In the United States, if these conversion kits are used in a metal flare gun, the converted gun is considered to be a firearm by the ATF. If a rifled barrel insert is used, the converted firearm is classified as a pistol; if a smoothbore barrel insert is used, the converted firearm is classified as an AOW subject to the additional requirements of the NFA. Flare cartridges are low pressure compared to conventional ammunition and even metal flare guns are not designed or intended to be used
