One thing leads to another, and here we have the De Havilland Vampire. A funny looking airplane. Second British jet fighter. Front portion of fuselage is made of wood, which is more than a little scary when you find out this thing can go 500 MPH, carries four 20 mm cannons (!), and can reach 40,000 feet in altitude. More than 3,000 of these things were built.
This engine used a centrifugal compressor instead of the axial flow compressor that we use today.
Here's a more recent color video. The owner disabled embedding so it's there instead of here.
