The Luftwaffe were the first to produce a jet fighter. The Me 262 began operations in 1944. Able to outrun anything in the air, Me 262’s tore into Allied bombers with impunity. The Allies responded by attacking factories and airfields.
Walter Hughes was the pilot of one of six USAAF Liberator bombers on a raid on Hamburg when attacked by Me 262s. "In a single pass we lost three B-24s in less than 10 seconds." Another said the 30mm cannon shells "ripped a hole big enough for a truck to drive through." (Tail End Charlies", (2004) Nicholl & Rennell)
