AN RAF engineer who was part of the Red Arrows aerobatics team was killed when one of its jets crashed in Holyhead, north Wales, yesterday.
The pilot survived after ejecting from the Hawk aircraft and was receiving medical care.
Eyewitnesses described seeing a fireball and dark smoke.
It is understood there were two people on board the Red Arrows jet aircraft. The Ministry of Defence said it was investigating.
North Wales Police confirmed they were in attendance and were called at around 1.50pm.
"We are aware of an incident today at RAF Valley involving a Hawk aircraft," a Ministry of Defence spokesman said.
"We are investigating the incident and it would be inappropriate to comment further at this stage."
The Red Arrows Twitter account said: "We are aware of an incident today at RAF Valley involving a Hawk aircraft. We are investigating the incident."

"We sent an emergency ambulance and a Wales Air Ambulance to the scene."
Caterer Anne Wilson, who works at The Anglesey Golf Club, situated at the end of the runway at RAF Valley, witnessed the aftermath of the crash.
The 52-year-old told the Press Association: "I did not see the crash but I heard a very loud noise.
"We are used to the planes going over but this was unusual, it was different to what we normally hear around here.
"I did go and have a look and there was a big fireball and lots of dark smoke ... quite a few of the members actually saw it.
"They said the plane came in quite steeply and saw a pilot eject, but that it was very low to the ground when they ejected."
She said the air ambulance was at the scene "for a very long time".
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
