"This is is a picture of a turbo jet engine that I worked on in Evandale, Ohio around 1969 or 70," advises Mister B. "It is set in a pod, as if you were standing on the ground looking up at it. The turbine is at the top. The compressor blades (compressors) are at the bottom. They spark the air and send out the exhaust which creates the thrust."
