Two RAF crew have been killed and one injured after their aircraft crashed on a training exercise.
The crew were flying a Canberra-type aircraft
The accident happened on the runway at RAF Marham, Norfolk, at about 2230 BST on Thursday during landing.
The jet, a Canberra T4, was involved in "touch and go" training, where the crew practise landing and take-off.
A Ministry of Defence spokesman said the next of kin were being notified and a board of inquiry would be set up on Friday to investigate the accident.
He said the third injured crew member did not have life-threatening injuries.
One of the crew managed to eject from the Canberra before it hit the ground, and he was taken to a Nottingham hospital with severe back injuries, it was reported.
"Emergency services responded quickly and are now at the scene. A board of inquiry will be convened to investigate the accident," RAF Marham Squadron Leader Rem Merrick said.
The runway would remain closed until the wreckage was removed and the scene examined.
The MoD spokesman added that RAF training takes place both night and day.
