We first earned that Google co-founder Sergey Brin was secretly building a “massive airship” inside of Hangar 2 at the NASA Ames Research Center back in 2017, but few details on the project have emerged since. Now, according to a report from the Telegraph, progress on the project appears to be picking up as Brin is currently soliciting aerospace engineers to work on his blimp from a hangar in Mountain View, California. From a report: At 656 feet in length, the massive craft is expected to be the largest of its kind in the world upon completion, and it’s reportedly costing Brin upwards of $150 million to construct. Some of that money will presumably go toward paying the $28 per hour salary and pension benefits Brin is offering entry level engineers to work on the project, according to the Telegraph piece, which notes that the job listing also requires that applicants be “comfortable working outdoors.”

As for why Brin wants to build this massive blimp, sources with knowledge of the project told The Guardian in 2017 that the Google billionaire plans to use craft as an intercontinental “air yacht,” ferrying his friends and family around the globe in style. The blimp will also find use on the other end of the privilege spectrum, according to those sources, who told the newspaper that Brin envisions using it to deliver supplies and food to remote locations on humanitarian missions.
