Google cofounder and Alphabet president Sergey Brin is secretly building a massive zeppelin in Hangar 2 of the NASA Ames Research Center, with a giant metal skeleton already in place, reports Bloomberg's Ashlee Vance.
It's not immediately clear if this dirigible is for business purposes, or represents more of a hobby for Brin.
According to the report, Alphabet has nothing to do with Brin's blimp project — though, as Vance points out, Google arm Planetary Ventures took over management of the NASA Ames hangars in 2015.
Earlier this week, Kitty Hawk, a venture backed by Brin's fellow Google founder Larry Page, revealed plans to start selling a personal "flying car" by the end of the year.
