The company, which was funded by Larry Page, is shutting down.

Sources inside the company said that Kitty Hawk had stopped work on the Heaviside vehicle. According to Insider, Page was more involved with the company's shift to research and development after the end of Heaviside.

Wisk Aero, the joint venture company between Boeing and Kitty Hawk, is still alive and well despite Kitty Hawk's decision to stop development of its own aircraft. Today's news won't affect Wisk. Wisk is in a strong financial and strategic position with both Boeing and Kitty Hawk as investors. Boeing invested $450 million into Wisk Aero at the beginning of the year.

A video of Kitty Hawk's "Flyer" personal transport vehicle was released ahead of another self-contained aircraft called "Cora" which became Wisk Aero.

The Flyer was one of the first vehicles to appear during an electric vertical takeoff and landing boom that eventually included others like Toyota-backed Joby Aviation and others. Larry Page is the owner of a flying car company called opener.

Even though the startup couldn't find a business path for the Flyer, it shifted focus to Heaviside.
