Rolls-Royce’s first all-electric plane has completed its maiden flight ahead of a world record attempt later this year. The Spirit of Innovation’s 15-minute flight took place at the Boscombe Down military testing site on Wednesday, powered by the most “power-dense” battery pack assembled for an aircraft, the company said. Rolls said the 400kW electric powertrain was equivalent to 500 horsepower. It will be used in a bid to set a new world record for an electric flight speed of more than 300 miles an hour with the plane later this year. The current record stands at 210mph.
