Vomit? Well, occasionally, I suppose, but that malodorous condition can be found in pretty well any aircraft that has not properly been washed out. Perhaps more noticeable in a Chipmunk due to the canopy - I suspect many more people were sick in its predecessor (DH82a) but less noticeably so due to the natural ventilation afforded by the open cockpits. Having a passenger on board while you practise recovery from unusual attitudes on instruments is guaranteed to produce something unpleasant.
My olfactorial memories are of leather, sweat and Brylcreme. But I'm from a different age when you had to do a couple of low passes in your DH89 or Lockheed Lodestar to move the dinosaurs off the landing strip. Happy days!
Incidentally, why has nobody mentioned the Stampe? It had a better rate of roll than the Tigger, didn't have those damned slats and was nicer to fly. But if you want a lesson in energy management, have a go in the Fournier RF4 . . . .
