Yes, tragically two crew have been killed in an Defence Flying Training School Squirrel. Not sure of the background, or whether this was a training sortie, but looks as if they may have hit power cables - Certainly the crash brought down some power lines, or they were switched off to allow recovery at the scene.
Accident site was in Devon. See this report from the BBC

As always, a terrible loss.
