Dubai again is planning for the takeoff of flying taxis in this futuristic city-state on the Arabian Peninsula, offering its firmest details yet Monday for a pledged launch by 2026.

Since 2017, the commercial capital of the United Arab Emirates has already home to the world鈥檚 tallest building and other architectural wonders. A series of different types and companies have cycled through those promises as well, most timed to be included at Dubai鈥檚 annual World Government Summit, which saw this year鈥檚 edition begin Monday.

Dubai鈥檚 ruler, Sheikh Mohammed bin Rashid Al Maktoum, announced the relaunched flying taxi program on Twitter Sunday. This time, Dubai highlighted the six-rotor electric flying taxi made by Joby Aviation of Santa Cruz, California, in the promotional video.

The inclusion of Joby Aviation, rather than the Chinese-made EHang 184 and or the German-made electric Volocopter all previously displayed in Dubai, wasn鈥檛 explained by Emirati officials. Joby aircraft featured at a stand at the World Government Summit on Monday.

鈥淲e鈥檙e excited about the opportunity and actively exploring the possibility,鈥� said Oliver Walker-Jones, a spokesman for Joby Aviation.

Ahmed Bahrozyan, an official in the emirate鈥檚 Roads and Transport Authority, similarly told the state-owned Dubai Eye radio station on Monday that 鈥渋t鈥檚 early days鈥� for the plan.

鈥淲e haven鈥檛 yet signed with any partners yet,鈥� he said.

Another difference in this year鈥檚 promise on flying taxis is the release of specifics about the program. The city plans four 鈥渧ertiports鈥� by Dubai International Airport, the world鈥檚 busiest for international travel, downtown Dubai, the manmade Palm Jumeirah archipelago and Dubai Marina. Those points will include two launching pads and four charging points for the flying taxis.

鈥淲e believe those are attractive areas with business hubs and tourist hubs that could generate considerable demand,鈥� Bahrozyan said.

The pricing for the flying taxis 鈥渨ill be in the range of a limousine service in Dubai, maybe slightly higher,鈥� Bahrozyan said. The RTA describes limo services rates as 鈥渁t least 30% higher than taxi fares鈥� in the city. Taxis have a minimum fare of around $3.25 and charge $0.50 a kilometer.

Another departure from earlier plans include the RTA planning to have piloted flying taxis at first, rather than autonomous ones as previously discussed. Dubai officials described the taxi as having a pilot with four seats for passengers on board, which match Joby鈥檚 electric flying taxi. However, Bahrozyan said tests would continue with autonomous flying taxis as well.

The Joby prototype can fly over 240 kilometers (150 miles) before needing a charge 鈥� something which would put Abu Dhabi and other areas of the country within range. It takes off and lands vertically, while its rotors tilt forward in flight. It has a maximum speed of 320 kph (200 mph).

Joby Avation Inc., which is listed on the New York Stock Exchange, was at $4.20 a share before trading Monday. Its major shareholders include Intel Corp., while Atlanta-based Delta Air Lines also has invested.

The video posted by Sheikh Mohammed鈥檚 Twitter account also included the logo of London-based Skyports Infrastructure, which also refers to its support projects as 鈥渧ertiports.鈥� The company already is testing its 鈥渧ertiport鈥� model outside of Paris and is working with Joby. Skyports did not immediately respond to a request for comment.

Opening the skies to flying taxis would add to the 鈥淏lade Runner鈥� skyline of Dubai, while also easing the real-world grind of daily traffic that鈥檚 only worsening

Rush hour on Sheikh Zayed Road, a dozen-lane artery running down the length of the Dubai, alternates between dense gridlock and sports-car slalom. Over 1.8 million Dubai-registered vehicles ply its roads, not counting those crowding in from the United Arab Emirates鈥� six other sheikhdoms.

There鈥檚 also the desire to move away from carbon-belching gasoline and diesel vehicles as . That鈥檚 even as the Emirates hopes to expand its production of crude oil ahead of a promised 鈥渃arbon-neutral鈥� future by 2050. Meanwhile, .
