How are hot air balloon pilots licensed?
Hot air balloons are registered like any other aircraft and are subject to regular airworthiness checks. C.A.S.A. (Civil Aviation Safety Authority) will not allow a hot air balloon to be certified as airworthy unless these inspections and checks are done by authorized maintenance personnel and certified by them. All hot air balloon pilots are licensed by the C.A.S.A. and have to pass regular flight checks.
