By adding a keel and framework blimps became much bigger. Using engines and propellers the blimp can go up, down and forward. Controls help the blimp stay straight and steady. A blimp can fly against the wind. Some blimps crossed the Atlantic ocean carrying passengers.
People usually ride in a gondola, a large box or room under the blimp.
Long ago many people wanted to ride in blimps to go places. Airplanes were not yet carrying passengers. Most people have seen the Goodyear Tire and Rubber Company blimp and maybe the Fuji Camera Films blimp. Sometimes, if you are at a sports event you will see a blimp above the stadium. Other people rent a blimp to go sight seeing.
