My embarked helicopter flight did the odd school visit for
PR purposes. One time we were tasked to land at a small school on the Queensland coast. With the Observer navigating we found the school without too much trouble and duly landed on the oval. We were soon surrounded by school kids, teachers, dogs, etc. Gave a very impressive talk about the helicopters capabilities, explained how the pitot tube wasn't actually a gun, took photos with kids wearing helmets, chatted up the female staff,etc etc. After half an hour one of the teachers asked "why are you here anyway?" Oops-wrong school.
