An inquiry into a North Sea helicopter crash is due to begin, almost five years after the disaster in which 16 people died, including a man from Norwich.
Relatives of those who died on board the Super Puma are expected to attend the fatal accident inquiry in Aberdeen.
Nolan Goble, 34, from Norwich, was among14 oilworkers and two crew who died in the crash off the Aberdeenshire coast on April 1, 2009 .
The inquiry is expected to last about six weeks and will examine the circumstances of the crash in order to prevent any future tragedy.
The helicopter was returning from BP's Miller platform when the aircraft's main rotor gearbox suffered a "catastrophic failure".
