Three independent reports give the New Glenn factory in Florida as 750,000 square feet, not 650,000. These are Space.com in December 2016 (E3), and GeekWire in October 2018 (E2) and March 2019 (E1). E2, published about two weeks after the claim date, says the 750,000-square-foot factory was already built. The 650,000 figure is about 13% below the reported size, which falls in the 10–25% band the criteria set for mostly false.
