Silicon Valley aviation startup accuses Larry Page-backed rival of stealing secrets

A legal dogfight is raging in Silicon Valley — with two deep-pocketed startups accusing each other of stealing futuristic airplane designs.

Archer Aviation — which archrival Wisk Aero sued this spring for allegedly stealing its plans for an electric-powered “air taxi” that’s capable of flying like both a plane and a helicopter — fired a legal salvo on Thursday claiming that Wisk is actually the real thief, The Post has learned. Wisk — whose high-profile backers include Boeing and Google co-founder Larry Page’s company Kitty Hawk — first sued Archer Aviation in April, claiming it used designs stolen from Wisk to woo investors and drive up the value of a $3.8 billion blank-check deal it announced in February.
