Ballon Buster and Blue Max... Non-Combat Incidents Claim Two German Aces in Two DaysFirst to fall was Friedrich Friedrichs of Jasta 10. Ranking among Germany's top-scoring balloon busters and a candidate for the
Pour le Merite, Friedrichs met his fate after the incendiary bullets loaded on his Fokker DVII spontaneously caught fire. Though he parachuted, his harness became entangled with his plane's tail and Friedrich was dragged to his death.
Hans Kirschstein of Jasta 6 died the next day. He received the Blue Max just three weeks before his demise as a passenger of a Hannover CL on a routine maintenance fight with an inexperienced pilot. A remarkable dogfight involving Kirschstein occurred earlier in March 1918, when a lone AW FK.8 (piloted by Canadian 2nd Lt. Alan McLeod, with observer Lt. Arthur Hammond) encountered nine Fokker Triplanes. The duo shot down four Fokkers until Kirschtein strafed them thoroughly, setting the FK.8 aflame. The rest of the story via wikipedia:
McLeod instantly pushed her over into a very steep side-slip, but the flames were scorching him, and so he jumped out of his cockpit on to the left wing and crouched low, with the joystick pulled hard over in his right hand. Then he smashed a hole through the fabric in the fuselage so that he could reach the rudder-wire with his left hand, and so he guided her towards the lines. In this way he kept the flames away from his wounded observer and prevented the aircraft from burning up. When the machine finally crashed in No Man's Land, the young pilot, not minding his own injuries, dragged his comrade from the burning wreckage and under heavy fire carried him to comparative safety, before collapsing from exhaustion and loss of blood.Hammond was wounded six times and ultimately lost a leg. McLeod, wounded three times, earned the Victoria Cross. He returned to Manitoba to recuperate but soon died in the Influenza pandemic.
