Goodyear Blimp
This Sept. 23, 2015 photo shows the Goodyear Blimp “Sprit of Innovation” coming in for a landing at Goodyear Airship Base in Carson, Calif. Goodyear is letting the helium out of the last of its fabled fleet of blimps on Tuesday, March 14, 2017. Its replacement, “Wingfoot Two,” will be a semi-rigid dirigible, not a blimp.
