The Goodyear blimps may be the best-known corporation symbol in the United States. Thomapyrin Thermal Blimp Modern technology has produced an economical alternative for companies advertising with a much smaller budget than Goodyear's. The key feature of a thermal airship design that reduces initial cost and operating expense is the use of hot air instead of expensive helium gas. Eliminating the helium and using a pressurized envelope to attain the blimp shape allows a hot air airship to be deflated between flights and easily packed into a small trailer for transportation and storage. Gone are the large traveling ground crews, mooring masts and large hangers.
Thermal airships are quite popular in Europe and are being used by a growing number of advertisers.
Recently Goodyear added two thermal airships to their fleet of gas blimps.
