The P-61 was built in response to the Blitz on Great Britain, in 1940. The RAF were in need of a night fighter and they confirmed with their US counterparts on the specifications. The result was a twin tail plane with a crew of three, it was specifically designed to house a radar to zero the aircraft in, at night on their target.
Only four now survive.
Joining me is Russell Strine from the Mid Atlantic Air Museum, in Pennsylvania, who are currently restoring one, the intention is to get it in the air once more.
