The RAF is investigating after a jet belonging to the Red Arrows display team crashed in Wales.
The Hawk aircraft is thought to have crashed early this afternoon near the RAF Valley base in Anglesey and two people ejected, according to a witness.
An RAF spokesman said: “We are aware of an incident today at RAF Valley involving a Hawk aircraft.
“We are investigating the incident and it would be inappropriate to comment further at this stage.”
The Red Arrows tweeted: “We are aware of an incident today at RAF Valley involving a Hawk aircraft. We are investigating the incident.”
Deno James, a pipe welder for O’Connor Utilities, saw the aftermath of the crash and said: “I was near the compound and the plane came around to do a practice landing on the runway.
“It missed the runway and landed at the left hand side. Two pilots were ejected about 200 yards from the ground.
“I pulled up for a moment in my truck watching and watched the plane come over my head.
“I know it was a Red Arrow because I’ve seen them at an air display before.”
Paramedics and an air ambulance were called to the base.
A Welsh Ambulance Service spokeswoman said: “We were called shortly before 1.30pm this afternoon to reports an aircraft had crashed at RAF Valley in Holyhead.
“There is an emergency ambulance and a Wales Air Ambulance at the scene.”
RAF Valley is home to No 4 Flying Training School, which trains pilots in mountain and maritime warfare. The military’s Mountain Rescue Service is also based there.
In total about 1,500 people work at the base.
