Everything Electric TECH sits down with David King, chief engineer at Vertical Aerospace, for a long look at how electric flight went from pipe dream to flight-test program. The Bristol company, founded by Stephen Fitzpatrick in 2016, builds an eight-rotor winged aircraft that takes off and lands vertically. The prototype the show visited in 2022 was the VX4, and the production version is called Valo. King's argument is that batteries, not motors, are what changed the picture. Once energy and power density crossed a threshold, an electric vertical-takeoff aircraft that could hover, cruise on a wing, and still hold power in reserve for an emergency became not just possible but, on his numbers, cheaper to run than a helicopter.
Vertical is not doing this alone, which is the part the interview mostly leaves out. It is one of several developers racing the same certification gauntlet. In the United States, Joby Aviation and Archer Aviation are further along the FAA's process and both aim to begin US operations under a federal pilot program. Vertical has said it targets certification of Valo with the UK CAA and EASA by the end of 2028, the timeline reported around the aircraft's December 2025 unveiling. What separates this class from earlier electric-flight hype is that regulators wrote a specific airliner-grade safety standard for these aircraft, and the companies designed to it from the start. That shared bar, more than any single spec sheet, is why this generation is being taken seriously in a field where past electric-aircraft promises quietly went nowhere.
King tells the show the aircraft certifies to a one-in-a-billion safety standard, the same 10 to the minus 9 target used for airliners, and that electric propulsion makes that reachable by trading hundreds of critical mechanical parts for a smaller number of wires, chips, and motors. He explains the tilt-rotor layout: eight propellers provide a vertical lift that lasts only seconds, then four tilt forward for wing-borne cruise, which he says needs roughly a quarter of the takeoff power and drops the noise sharply. He describes flights over the company's test center that he says sound like a distant jet rather than a helicopter. On batteries, he frames replacing a pack every year or so on a high-use aircraft as still cheaper per seat-mile than maintaining a helicopter's gearboxes and turbines. All figures are as presented in the interview.
Bottom line: The engineering case here is genuinely strong, and King is a clear guide to why quiet, electric, runway-free flight is closer than it sounds. The honest caveat is the one aviation keeps relearning: certification timelines slip, and a 2028 target is a target, not a delivery date. Watch two things over the next year, funding runway and flight-test milestones, because those, not the physics or the noise, are what decide whether Valo becomes a service or a very sophisticated demonstrator. For now, cautious optimism is the right setting.
