The first jet fighter to enter service and see combat anywhere in the world, the Messerschmitt Me 262 was a deadly technological marvel – yet it was also difficult to produce, dangerously unreliable and extremely vulnerable during takeoff and landing. Despite these flaws, its graceful swept wings, aggressive shark-like profile and undoubted combat abilities made it a legend. The aircraft underwent rapid development during its short front line career and numerous unusual variants were designed and produced.
