Twenty-seven minutes. That’s how long the largest battery-powered aircraft ever built stayed in the air — and it might turn out to be one of the most important half-hours in aviation history.

Heart Aerospace founder and CEO Anders Forslund was at the controls of the 11-ton X1 for its historic test flight, conducted under Federal Aviation Administration oversight. The aircraft climbed to 335 meters, ran its electric motor at more than a megawatt of power, and completed a full flight cycle: taxiing, takeoff, in-flight maneuvers, and a soft landing.

Then came the number that will stick in your head. The electricity for the entire flight cost about five dollars — roughly 100 Swedish crowns. Hold that thought; we’ll come back to it.

What the X1 actually proves

Let’s be clear about what this is — and what it isn’t. The X1 will never carry a single passenger. It’s a technology demonstrator, built to test the powertrain, the software, and the processes that will feed into Heart Aerospace’s real product: the ES-30, a 30-seat production aircraft.

But that framing undersells the moment. “We’ve proven that electric flight is possible at the scale of a conventional commercial airliner,” Forslund said. Until the X1, battery-electric aviation lived in the world of two- and four-seat trainers and tiny prototypes. An 11-ton aircraft with megawatt-class propulsion is something else entirely. It’s proof the core engineering challenge — moving serious mass with batteries — can be solved.

For comparison, hybrid-electric prototypes like the Nimbus quarter-scale testbed are pushing in the same direction. But the X1 is flying at full size, under FAA oversight, right now — and full size is where the hard engineering questions live.

The ES-30: where this is actually headed

The X1 exists so the ES-30 can exist. Heart’s planned production aircraft seats 30 passengers and goes hybrid-electric: roughly 200 kilometers on pure battery power, stretching to 800 kilometers with its gasoline generators running.

That range profile tells you exactly which market Heart is chasing. Short regional hops — the routes where turboprops dominate today and where fuel costs eat operators alive. The company estimates the ES-30 will cut airlines’ operating costs by more than 40% compared with older turboprop aircraft. On thin regional routes where margins are already razor-thin, that number changes the entire business model.

The order book backs up the pitch: nearly $10 billion in commitments. Key partners and investors include United Airlines and Air Canada, with SAS and regional Scandinavian and British carriers also showing interest. First production aircraft begins flight testing in 2028; full commercial service is targeted for 2031.

That’s a patient timeline, and it’s the right one. Certification is where electric aviation startups usually die — the paperwork takes longer than the engineering. By moving to Los Angeles and working inside the FAA system from the start, Heart is front-loading the hardest part. The X1’s FAA-overseen flight cycle wasn’t just a test of the aircraft; it was a rehearsal of the certification process itself.

A Swedish company with an American future

Heart’s story has an interesting wrinkle. Founded in Gothenburg, Sweden, the company shut down its Swedish division in April 2025 and moved its headquarters and production entirely to Los Angeles — drawn by more flexible certification rules and proximity to capital.

That move says a lot about where electric aviation is heading. The technology may have European roots, but scaling it needs American regulators and American investors. Five years ago, a battery-electric airliner was a research project. Now it’s a Los Angeles manufacturing bet with $10 billion in orders.

Why five dollars matters more than 27 minutes

Skeptics will point at the obvious: 27 minutes, 335 meters, one test flight. That’s fair. Batteries are still heavy, energy density still limits range, and certification is still a long road.

But the cost figure is the one to watch. Roughly five dollars of electricity for an 11-ton aircraft’s test flight isn’t just a curiosity — it’s a preview of an operating-cost advantage that compounds across every flight, every day, across a fleet. Aviation’s eternal problem is fuel. If electricity can replace even part of it, the economics of flying get rewritten from the bottom up.

What it means

For travelers: The 200-kilometer pure-electric range covers a huge share of short regional hops. Expect the first passengers to board quieter, cheaper flights on routes that today run on aging turboprops — regional Scandinavian routes are the likely proving ground.

For cities and airports: Electric aircraft are quieter and cleaner on the ground and in the climb-out phase. Airports near communities, which constantly battle noise complaints, have real reason to cheer this along.

For investors: The ES-30 timeline (flight testing 2028, service 2031) is aggressive but concrete, and the order book is real money from real airlines. Electric aviation just grew up a weight class — and the broader Breaking News record shows the momentum is one-directional.
