Pilotless flight trialled in UK shared airspace
A Jetstream aircraft became the first to fly "unmanned" across UK shared airspace last month.
An on-board pilot handled the take-off, from Warton, near Preston in Lancashire, and landing, in Inverness.
But during the 500-mile journey, the specially adapted plane was controlled by a pilot on the ground, instructed by the National Air Traffic Services.
Peter Marshall spoke to Lambert Dopping-Hepenstal, programme director of the Astraea consortium organising the flight, inside the historic plane.
