The GZ-20 was introduced as part of a US$4 million expansion program by Goodyear in 1968 that included the construction of a new GZ-19 Florida-based airship (Mayflower N1A), replacement of the California-based GZ-19 with a GZ-20 (Columbia N3A), adding a third airship to the fleet (GZ-20 America N10A) and constructing a new airship base at Spring, Texas as home to the new blimp.
Columbia, tail number N10A, was buzzed repeatedly by a radio-controlled model airplane when the blimp flew over a field used for R/C model flying on September 3, 1990; the R/C pilot then intentionally rammed his model airplane into the blimp, tearing a three-foot hole through the envelope. [38] The blimp made a "hard landing" at a nearby airport.
N2a cells have been used to study neurite outgrowth, [1] neurotoxicity, [2] Alzheimer's disease, [8] asymmetric division of mammalian cell lines, [9] adenoviral transduction, and the diagnosing of rabies. One specific research applications is the differentiation of N2a cells into dopamine neurons for potential use in treating Parkinson's Disease.
The B-class blimp, for which 20 were built for patrols during World War I. The C-class blimp, 10 were built near the end of World War I. Six D-class blimps were built in the 1920s, the last was retired in 1924. Only one E-class blimp was built in 1918 and retired in 1924. One F-class blimp was built in 1918 and retired in 1923. [4] World War 2:
The initial version, designated ZPN-1, was a follow-on to the M-class blimp for patrol missions. The Nan ship used a significantly larger envelope than the M-ship although their overall lengths were similar. Two Wright R-1300 Cyclone 7 single-row, air-cooled radial engines powered the N-Class blimps. [2]

The Conan blimp was an orange dirigible owned by Turner Broadcasting System for the purpose of promoting the premiere of Conan O'Brien on his late-night talk show, Conan, on TBS. Background [ edit ]
The D class blimp was a patrol airship used by the US Navy [1] in the early 1920s. The D-type blimps were slightly larger than the C-type and had many detail improvements. The Navy continued the practice of dividing the envelope production between Goodyear and Goodrich. The control cars were manufactured by the Naval Aircraft Factory
