21st Century Airships

21st Century Airships was founded by Hokan Colting in the mid 1990's. Mr. Colting was the founder of Colting Balloons which later merged with Thunder Balloons to form the legendary Thunder & Colt. After relocating to Canada in the 1980's he began the development of a sperical airship. Forward motion and control are achieved by deflecting the twin engines' thrust with deflector vanes. The pilot and passengers are located inside the spherical envelope and enjoy a good view through panoramic windows.

Two manned prototypes are currently flying. The SPAS-4 demonstrator (C-FRLM) has a volume of 41,500 cu.ft. (1,180 cu.m.). It is a 43' (13.1 m.) diameter sphere and seats the pilot and one passenger. The SPAS-4 airship is powered by two 50 hp. engines. The newest 21st Century airship is a pre-production model used for type certification. It is of the SPAS-70 type and registred C-FYOK. It has a volume of 91,000 cu.ft. (2,595 cu.m.). This ship is a 56' (17.05 m.) diameter sphere which seats the pilot and 3 passengers. This airship is powered by four 100 hp. engines. The first test flight with SPAS-70 was made on August 8, 1997.
