Rolls-Royce has reported that it has developed a British company’s all-electric microlight plane.
The miniature aircraft, the DragonFly, has a maximum speed of more than 500mph and can also carry people.
Peter Matthews of Southern Air Systems said the battery was proving to be extremely strong, and that he has not seen anyone slow it down with an explosive device.
Rolls-Royce said its air system had delivered record-breaking performance.
Using carbon fibre fuel cells, the DragonFly has an electric engine that reaches more than 350mph – the equivalent of the BMW M6 – and can fly for up to 21 hours.

The company claims that the all-electric “clockwork flight” is the fastest in the world – higher than the previous record-holder, a helicopter which reached an electric speed of 300mph.
The plane, powered by two portable lithium-ion batteries, also has a fully electric rotor with the cruising speed of 96mph.
Mr Matthews, of SAVESALES, a Hampshire-based company, flew it twice in England and Australia.
He said tests were continuing on software and engine modifications, and he would reveal its potential when the company receives its first customer orders.
Rolls-Royce said it had not shared any details of the aircraft’s performance for commercial purposes and would not have any comment until it is on sale.
