want need one of these thingies…
My uncle had something better.
He was Senior Technical Officer at an RAF Strike Force base at the height of the Cold War in the 1960s with 2 aircraft on Quick Reaction Alert (hit the starter and go).
He got hold of a jet engine, bolted it down on a trolley and ran it up and down the runways in winter.
Come to think of it, I think I’d rather have one of those…
