Nav School in the early 70s was effectively training Lancaster navigators for an RAF equipping with F4s, Buccaneers and Nimrods. I hated it.
Worked well for me. After getting through nav school (1970) I spent the next six years operating kit much of which would have been recognisable to a Lancaster navigator. They never let me get near an F4 or a Buccaneer - probably a wise decision!
