They are replacing the blimps with Zeppelin NTs designed by Zeppelin Luftschifftechnik (ZLT) of Friedrichshafen, Germany. It is amazing that ZLT is still in business after all this time. There have not been commercial zeppelins since the Hindenburg as far as I know. The Hindenburg was a marvelous way to travel, by all accounts. Except for the explosion. It was spacious, luxurious, quiet, and so smooth the crew would leave a glass milk bottle upside-down in the foyer, and it would not topple over the whole trip. It was so quiet, one passenger did not realize it was airborne. She thought it had not left yet. Hydrogen was not a good choice. 22 civilian hydrogen airships exploded: http://www.airships.net/hydrogen-airship-accidents That is not counting the military zeppelins shot down during WWI, in bombing raids over England. - Jed
