The Sea Vixen was a carrier bourn aircraft flown by the Royal Navy from1959 till 1972. Unusually the Sea Vixen had a twin boom airframe, something which seemed to be favoured by de Havilland and reminiscent of their very first jet fighter, the Vampire, but much bigger and I thought a lot scarier looking. Judge for yourselves, watch this YouTube clip of opertional aircraft:

This example stands at the de Havilland Aircraft Heritage Centre established in 1959 and run by a dedicated team of volunteers who also do all the restoration themselves.
