I recall, many years ago, the Patrouille de France arriving at RAFC Cranwell in their FMs.
After refuelling, they taxyed to their parking slots with the groundcrew happily perched on the wing - that had the Jet Provost line chiefs choking on their tea!
It was quite amazing how both the Patrouille de France and the BAF Diables Rouge put on the superb displays they did back then, with these motor gliders powered by a couple of APUs!
