The Red Arrows jets and Typhoon warplanes have been grounded after concerns about a safety issue with the ejector seats.
They were grounded for all but essential flying as checks were carried out into the “technical issue”, which it was feared “may affect the safe operation” of the ejector seats, the RAF said.
The Red Arrows was forced to cancel a display at the Farnborough Air Show, but was given the all-clear late on Friday.
