The ground was shaking........

During my tour of duty in Germany back in 74-76, working the F-4 Phantoms, the F-15 was just coming into the Air Force inventory.
All us Phantom guys thought thought that aircraft was **** hot, as the F-4 was around for a long time.
Then around the later 1970's the Air Force wanted to send me to Okinawa, for another long tour of duty, when they started to send the first squadron of the F-15 to that island.
I got out of the Air Force, so never worked on them.
