An RAF jet has crashed at an airfield on Anglesey, shortly after take-off from the airforce base at Valley.
The pilot ejected during the incident at the Mona airfield involving an RAF Hawk aircraft at 1225 BST.
He was the only person on board the two-seater jet and was flown to hospital in Bangor but later discharged.
An eye witness said he saw the pilot land in trees and his seat end up in a nearby field.
The RAF said it was investigating the cause of the crash.
The Hawk was on a routine flight to report on weather conditions in the area when the incident happened.
Dennis Morris, 68, who lives near the crash site, told the BBC News website he heard a noise "like a horrendous car crash with the screeching of metal".
Mr Morris said he saw the crashed jet broken in two.
He added: "I looked out the bedroom window and saw the pilot was lying in a nearby field.
"He wasn't moving at all - he appeared to be quite badly injured."
Four fire engines and three other vehicles have been deployed to Mona airfield, which is eight miles away from the RAF Valley base, by North Wales Fire and Rescue service.
The pilot was discharged after treatment at Ysbyty Gwynedd, Bangor
A spokeswoman for North Wales Police said initial reports suggested the pilot had ejected safely from the plane and landed in a field before it crashed.
Squadron Leader Mark Byrne, a spokesman for RAF Valley, said details of the pilot's injuries were not yet known.
He said: "I can confirm that a Hawk aircraft has crashed at RAF Mona, which is a small satellite airfield connected to RAF Valley.
"We will not speculate about the cause of the accident as an investigation will be carried out to establish what has happened."
