Everyone making eVTOLs — Joby, Archer, Lilium’s ghost, Volocopter’s ghost, Eve, Vertical Aerospace — faces the same problem nobody wants to talk about: even if you successfully build the aircraft, where, exactly, does it land in a city?

The honest answer used to be: nowhere. Most cities have one or two helipads, all of them at hospitals or on top of corporate buildings, none of them ready to handle the volume of traffic an urban air-taxi service needs. New-build vertiports cost $25-50 million and take five years to permit. Until last month, the entire $12-billion eVTOL industry was a brilliant aircraft solution to an unsolved real-estate problem.

A young company in Dubai has just demonstrated what may be the actual answer. They call it Aeroberm. It is, structurally, a giant rooftop berm.

Why no one has solved the landing-pad problem

Joby has been certifying its eVTOL since 2020. Archer is in the same race. The aircraft work. They have been flown thousands of times. They have FAA Type Certificates pending. The pilots are trained. None of this matters if there is no place to land them.

The vertiport problem is half political (helipads in cities are noisy, expensive, and reviled by neighbours) and half engineering (you can’t just put a slab on a building and call it a heliport; you need approach paths, emergency egress, ground handling, charging infrastructure, fire protection, and crowd management). Urban-air-mobility advocates have been talking about “hundreds of vertiports per city” for a decade. The actual number deployed across the world right now is in the low double digits.

Aeroberm is built differently. The whole pad — landing surface, charging connector, fire-suppression, ground-handling tracks, passenger entry/exit, sensor array, lighting — is a prefabricated modular unit. It bolts onto an existing rooftop in roughly six weeks. It comes with its own approach-path software and is certified to handle the four eVTOL airframes the FAA and EASA are closest to approving: Joby S4, Archer Midnight, Eve EVE-100, and Vertical Aerospace VX4.

The Dubai demonstration

The first Aeroberm pad was installed in mid-May 2026 atop a 32-storey commercial tower in central Dubai. Test flights ran for ten days under Civil Aviation Authority supervision. The pad handled 240 successful landings and takeoffs by a Joby S4 demonstrator, with average ground-turnaround time of 9 minutes 30 seconds per aircraft.

Three orders are already on the books. Joby has bought 28 Aeroberm pads for a Manhattan-to-JFK network slated for 2027. Skyports has signed a Letter of Intent with the city of São Paulo for 18 pads on commercial rooftops. Dubai Holding has authorised six more across the Emirate, with operational service starting in late 2026.

What this means for urban air mobility

The financial impact is the part the eVTOL industry has been waiting for. With Aeroberm-class infrastructure, the route-economics for an air taxi service look very different. JFK–Manhattan, which Joby quoted at $250 per trip on a custom-built vertiport network, drops to roughly $90 per trip on Aeroberm rooftops. That puts urban air mobility into competition with helicopter taxis, premium ride-share, and high-speed trains — not as a luxury, but as a credible commercial product.

It also flips the schedule on the entire eVTOL industry. Joby’s 2027 New York service was contingent on its custom Manhattan vertiport. With Aeroberm, the service date moves up to mid-2026. Archer’s Los Angeles plans accelerate similarly. The aircraft were never the bottleneck. The places to land them were. That bottleneck may have just broken.

The eVTOL industry has burned $12 billion to date without flying a paying passenger. The next 18 months will decide whether that capital was visionary or vapour. The bet rests, more than on any aircraft, on whether the world’s rooftops can become airports faster than the planning departments thought possible.
