This time around, though, Kitty Hawk's ambitions are bigger. Like Kitty Hawk's Cora, many rely on drone technology and vertical takeoff and landing, so they don't need a runway.
Capacity: Designed for two passengers.
Testing of a self-piloted air taxi is taking place in Canterbury, with the hope the flying service could soon take to the skies.
An "air taxi" developed by Page's Kitty Hawk company, the electric aircraft is intended for use as part of a transportation service instead of sale to individual users.
Range: Initially about 62 miles / about 100 kilometres. As the New York Times explains, today the company will join with New Zealand Prime Minister Jacinda Ardern to announce an agreement to test the vehicles there.
"Christchurch is committed to becoming carbon neutral and we are embracing future technologies in the areas of future transport, future foods, Antarctica and space technology, technical adventure clothing, social enterprise - we are open for business and making strong strides in these areas".
