A memorial to 13 people killed when their helicopter crashed into the North Sea has finally been unveiled - 33 years after the tragedy.
The aircraft had been travelling from a gas rig to Bacton gas terminal in North Norfolk on August 13 1981 when its pilot sent a distress message to report an engine failure.
Moments later, they lost contact and a search and rescue helicopter from RAF Coltishall was scrambled.
Among the 11 passengers and two crew who died in the crash off the coast of Happisburgh was 28-year-old Stephen Harvey.
His parents, Joyce and Paul Harvey, from Gorleston, near Great Yarmouth, have spent the past 33 years campaigning for a permanent memorial to the 13 men who lost their lives.
Today, they attended a special ceremony at St Nicholas' Church in Yarmouth - alongside Stephen's wife Jill - when it was finally unveiled.
The Westland Wessex operated by Bristow Helicopters was never fully recovered from the crash site.
An Inquest at the time recorded an open verdict stating there was insufficient evidence to determine the exact cause of the crash.
Despite many unanswered questions, Stephen's parents said today was, for them, the end of an era and that they felt great relief that the names of the 13 men who died in the tragedy were finally there for all to see.
