A woman who lost her son in a helicopter crash has donated £25,000 to the RNLI in his honour.

Oil worker Stuart Wood, 27, died when the Super Puma helicopter he was travelling in ditched into the North Sea in 2009.

Despite the efforts of RNLI volunteers from Peterhead, who were among the first on the scene, 16 people died.

Since Mr Wood's death, his mother Audrey has worked with her daughter Kerry to raise funds for the RNLI.

The pair have now presented the organisation with a cheque for £25,000 - bringing their fundraising total to more than £125,000.

Audrey, of Newmachar, Aberdeenshire, said: "I never envisaged raising money like this. It's making people aware that these very brave men are volunteers.

"I think a lot of people would expect them to arrive at an incident at sea and maybe forget these men might have just been sitting with their families having a meal.

"My introduction to them personally was seven years ago when I lost my son in the helicopter crash.

"I know it was an unsuccessful search, but it was the compassion and sincerity of these guys.

"They just must be made of something different. When they go out on a job, their whole heart is in it."

Their donation will go to RNLI stations in Aberdeen, Peterhead, Macduff, Fraserburgh and Buckie.
