I'd like to resurrect this thread for a moment to discuss a movie clip I once saw of the Northrup YF-17 at Farnborough (1974?). The Northup pilot, who was narrating the film, said he was a mite "hot and high" on downwind after finishing his routine, so he maintained a slip during his 180 to final.
I asked him afterward if he regarded that as an undue risk. He said "No, it behaves just like a J-3 Cub, I'm very comfortable in a slip with it."
(I've been slipping down final since my third hour of dual, 45 years ago.)
