Self-piloted flying taxis are being tested in New Zealand as part of a project backed by Google co-founder Larry Page that supporters say will revolutionise personal transport.
New Zealand regulators have approved plans for Zephyr Airworks, a subsidiary of Page's company Kitty Hawk, to develop and test the futuristic air taxis.
Known as Cora, the electric aircraft has a dozen lift fans on its wings, making it capable of vertical take-off and landing like a helicopter.
But developers say it is much quieter, meaning it could transport passengers in urban areas using rooftops and car parks as landing pads.
"We are offering a pollution free, emission free vehicle that flies dependably, we think this is the logical next step in the evolution of transportation," Zephyr chief executive Fred Reid said.
The Cora prototype being tested in New Zealand's South Island uses three on-board computers to calculate its flight path and is capable of carrying two passengers.
It has a range of 100 kilometres and can fly at 150 km/h at an altitude of up to 900 metres.
Zephyr said using the air taxi would be a simple experience for passengers, similar to taking a ride-share in a car.
"You wouldn't have to know anything about flying a plane. Cora could fly for you," it said in a promotional video.
"And it would be all-electric, helping to build a sustainable world."
It said Cora took eight years to design but then developers needed a suitable environment to safely test the new technology.
They settled on New Zealand because of its uncongested airspace and rigorous regulatory environment, with Reid saying local officials had embraced the idea.
"We had no idea what to expect," he said.
"They could have laughed us out of the room. We were pitching something that sounded like science fiction."
Cora has been given an experimental airworthiness certificate from the New Zealand Civil Aviation Authority.
Trialling the flying taxi service will reportedly take six years, with operations based around the city of Christchurch.
"This aircraft represents the evolution of the transport eco system to one that responds to a global challenge around traffic and congestion, and is kinder to the planet," Christchurch mayor Lianne Dalziel said.
