The Dark Story Behind the Merlin Engine – The Flaw That Almost Lost the Battle of Britain

In this video, we uncover the deadly flaw hiding inside the Rolls-Royce Merlin engine during the Battle of Britain — a simple carburetor design that killed power mid-dogfight and gave every Messerschmitt pilot a built-in escape route. We explore how Luftwaffe pilots exploited negative G to outrun Spitfires, why Rolls-Royce chose carburetors over fuel injection, and the motorcycle-racing engineer who fixed the problem with a brass washer the size of a penny. The woman behind the solution might be the most overlooked hero of 1940. #EngineeringHistory #WWII #RollsRoyce #MerlinEngine #BattleOfBritain #Spitfire #AviationHistory #MilitaryTech #WarHistory #EngineeringMarvels
