The de Havilland Sea Vixen was the first British two-seat fighter to ever break the sound barrier.Known initially as DH 110, it was one of de Havilland Aircraft Company’s earliest jet fighters. The aircraft was also famous among the Navy men for its immediately noticeable twin-boom tail and its unconventional cockpit layout.And while the aircraft exceeded expectations in its earliest stages and took part in the peak decade for the Fleet Air Arm and the Navy’s aircraft carrier force, as well as the overwhelming operation that halted Iraq’s plans to invade Kuwait, the Sea Vixen’s career was plagued with tragedy, intrigue, and even one more curious record.
