Think only ride that have paid for over the years is the SNJ-5 at White Waltham in 2014 where paid £600 for two 30 rides. But been lucky over the years and flown 13 other Harvards, 2 Mustangs, 2 Trojans, Provost, Avenger (oh yes paid the fuel for a JP ride) for nought or for services rendered in the UK….plus loads of other types 🙂
