The RAF has confirmed that an engineer has died in a crash involving a Red Arrows aircraft in North Wales. Emergency services were called to Holyhead just before 1:30pm this afternoon.
The Force say the pilot survived and is receiving treatment.
The Red Arrows aircrew had been at RAF Valley for routine Hawk simulator training, which takes place once a month.
They had just taken off from the base and were on their way back to RAF Scampton, where the aerobatic team are based.
Based at RAF Scampton in Lincolnshire, all Red Arrows pilots have flown operationally in frontline aircraft before joining the display team.
The Ministry of Defence has tweeted that the engineer's family have been informed.
The RAF has asked anyone who saw the incident to send photographs to email@example.com in order to help with the investigation.
