The Tech Is Finally Good Enough for an Airship Revival

LTA Research’s Pathfinder 1 aims to solve humanitarian-relief and supply-chain bottlenecks

At Moffett Field in Mountain View, Calif., Lighter Than Air (LTA) Research is floating a new approach to a technology that saw its rise and fall a century ago: airships. Although airships have long since been supplanted by planes, LTA, which was founded in 2015 by CEO Alan Weston, believes that through a combination of new materials, better construction techniques, and technological advancements, airships are poised to—not reclaim the skies, certainly—but find a new niche.

Although airships never died off entirely—the Goodyear blimps, familiar to sports fans, are proof of that—the industry was already in decline by 1937, the year of the Hindenburg disaster.

Today, what airships still linger serve primarily for advertising and sightseeing.
