Gizmodo just put up a pretty cool list of what they think are the most badass spy planes ever. Our favorite from the list? The Avro Vulcan B2(SR2) What does it do?
The Avro Vulcan was a four-engine jet-powered delta wing strategic bomber, operated by the Royal Air Force (RAF) from 1956 until 1984. In the mid Seventies nine Vulcans were adapted for maritime radar reconnaissance operations, redesignated as B.2 (MRR).
