I'm not sure that turning up at a school in a 50+ year old helicopter (albeit updated since 1968, but still a pretty old aircraft design), in order to tell a handful of pupils that they might be able to fly the thing in 6 years' time, would have them beating a path to the recruiting officer's door.....
At my prep school a Hunter pilot from Chivenor came to give us a chat, showing us a single seat liferaft, bone dome, oxygen mask, g-suit etc... Then he came back to visit a few days later - at 250ft and 420 kts! THAT was motivating!
