In 1978, a German company, Westdeutsch Luftwerbung, moved its 180 foot long flying machine to the United States, where it was leased by a consortium tentatively known as Skysign. The sides of the blimp are lined with 10,000 colored lightbulbs controlled by onboard computers, creating two 104 foot long flying billboards. The blimp’s powered by two 180hp Rolls Royces, cruises at 30 mph and never stalls. Its 211,888 cubic foot, helium filled envelope could carry it to 8,500 feet, but it’s happiest within a few thousand feet of the ground where its sign is visible to all.
