Question: are zeppelins and blimps the same thing?
Answer: What's the Difference? According to Airships.com: A dirigible is any lighter-than-air craft that is both powered and steerable (as opposed to free floating, like a balloon). Blimps like the Goodyear blimp, rigid airships like the Hindenburg, and semi-rigid airships like the Zeppelin NT are all dirigibles.
