Yes, the Google founders already have a Boeing 767 and a helicopter, so they decided it was time for another huge aircraft.
NASA Ames Research Center released the agreement (PDF) with a company controlled by Google cofounders Larry Page, Sergey Brin, and Google CEO Eric Schmidt. On page 37, the agreement lists aircraft that are allowed to land: a Boeing 767 (the existing Google Jet known about), two Gulfstream V executive jets, and a Boeing 757:
The B757 is not expected to operate from MFA before November 2007
Hmmm, so maybe there is something to Gary Price’s April Fool’s joke from 2005 about GoogleJet as an airline? ;-)
