After the failure of their innovative MB.2 to attract orders, James Martin and Captain Valentine Baker didn’t lose faith. The stunning MB.3 was their next attempt: A 2,000 hp Napier Sabre-powered fighter with the usual MB’s sturdy and clever construction methods heavily armed with its six 20 mm canons. Highly impressed, the authorities created the specification F.18/39 around Martin–Baker proposal. First flown by Captain Baker in the summer of 1942, the MB.3 delivered what it had promised. Sadly, barely one month after its first flight the prototype crashed due to engine failure taking the life of Captain Baker. After that the RAF lost the interest in the design due, it seems, to the delays already experienced and the perceived obsolescence of the MB.3 in the near future.
After the loss of his best friend, James Martin made of his life a crusade to invent and develop aircraft scape systems. The highly successful Martin-Baker line of ejection seat have saved almost 6000 lives since then.
A pugnacious piece of machinery, even unarmed.
