Like the B-52, the C-130/C.1 was designed in the 1950s, and other than some updates, is still basically the same aircraft that flew then. Actually, in the B-52's case, they're literally the planes that flew then. The C-130 is still in production.
The Gloster Meteor F8 (Prone) is an odd idea. It was built to assess any advantages that might be gained in dealing with G-forces -- while the pilot was lying down. It never made it past the test stage.
The tiny Messerschmitt Me 163 Komet. It's probably smaller than your car. They were rocket-powered to get them up to the incoming Allied bombers quickly. Then the idea was to glide back down and land on their single skid. That was the theory, anyway.
The last hangar, Hangar 1. It's a vast, open space with several large airplanes, including this, the world's first jet airliner. The Comet was ahead of its time. It also had square windows, which turned out to be a bad idea. This particular aircraft was originally sold to Air France, but after conversion to a Comet 1XB (round windows, a few other changes), it was given to Britain's Ministry of Supply and converted to a flying laboratory.
The smaller engine on the left is actually from the Concorde prototype, a Rolls Royce Olympus 593 turbojet capable of Mach 2. The much bigger turbofan on the right is a Rolls Royce RB 211. Interestingly, these engines are from roughly the same era (1969 and 1972, respectively), and generate roughly equal amounts of thrust (though efficient at much different speeds). The RB 211 has been used in a variety of aircraft, including 747 and 767s.
