Last time, I was with my list of 'Top Ten Flying Cars.' Let's talk about blimps this time. Blimps are a majestic and fascinating aircraft. While the Rigid airships do not depend on internal pressure to maintain their shape, the non-rigid airships are usually different from the moored balloons and are free flying aircrafts. Normally, Blimps rely on a higher pressure of the gas (usually helium) inside the envelope. Why the name 'BLIMP'?
