did you ever wonder how the non-rigid dirigible came to be called the "blimp?"
well, according to "dictionary of word origins," it so happened that "when england began experimenting with this type of airship in 1914, two designs were tested- the "a-limp" and the "b-limp." the a-limp was unsuccessful." (good thing.) "the b-limp was used and gave its name to all airships of this type."
