Have paid many visits to Fuerte as a holidaymaker. I cannot remember seeing anything relating to a Flying Club or Aircraft renting firm at the airport. If you 'Google' Fuerteventura, you may discover something I don't know of there, but in all my times on the Island, I can only remember seeing light aircraft [other than Police helicopter etc] on 3 otr 4 occasions. I suspect Lanza might be the same.
