Kittyhawk, the eVTOL technology innovator launched by Google co-founder Larry Page and senior Google executive Sebastian Thrun, is closing its doors. The California-based company, which since 2010 has been working on a variety of new electric and autonomous aircraft, announced via Twitter late yesterday that it has “made the decision to wind down” and that it is “still working on what’s next.”

The venture’s most current project has been the Heaviside autonomous eVTOL vehicle that last year received military airworthiness approval from the U.S. Air Force. Under the service’s Agility Prime program, the aircraft was being evaluated for potential military applications. Emergency medical support group Falck also was exploring how it might adapt Heaviside for first-response use to treat critically injured patients.

Kittyhawk is also the joint owner with Boeing of eVTOL aircraft developer Wisk Aero, which was established in 2019. The company did not respond to AIN’s inquiries anbout whether it will stay involved in Wisk’s plans to bring a four-seat autonomous eVTOL vehicle to market.
