Thanks a lot for your suggestions.
I've been to the airport myself to check the situation, unfortunately the container of the aeroclub du soleil seems to be abandoned.
I hope they've just relocated and not gone bankrupt but i'll try to reach them by phone.
I'm not SO fluent in french, but I'm italian so it's kind of close.. how did you solve this problem? I guess this guy was fluent in english as well being an airline pilot.. but I would need the PPL to be taught in English I guess
Do you still have a contact? If so, could you please send me a private msg?
Cheers!
