At the beginning of the television series, Sky flew a Cessna T-50 twin-engine “Bamboo Bomber.” The plane, a World War II surplus UC-78B, was owned by legendary Hollywood pilot Paul Mantz[4] and flown by employees of his Paul Mantz Aerial Services for filming of the flying sequences.[5] At least two other T-50s are known to have been used for on-ground and in-the-cockpit scenes as well as a Beechcraft in a lost episode.[6]
