Thirteen years ago, former Senior Aircraftman Greg Vickers suffered life-changing injuries after being found unconscious in the road, leaving his family with many unanswered questions. But now, he is taking on an incredible challenge to give back to the charity which has supported him throughout his recovery.
To this day no-one knows what happened to 23-year-old former Senior Aircraftman Greg Vickers to leave him unconscious in a road after a night out with friends. That was 2005 and his parents Ron and Eileen still do not have answers to their questions.
At the time they were told their son had been in an accident and suffered severe brain injuries. Greg was in a coma for nine weeks when he suffered a stroke which left him with permanent mobility issues and meant he had to spend a further seven months in hospital.
Ron and Eileen were about to retire but as Greg's disabilities meant he was unable to live independently, the couple became his carers. At this point, the RAF Benevolent Fund stepped in to help the family with finding suitable accommodation for Greg's needs.
But Greg, who lives in Wrexham, was determined to walk again and began his long road to recovery. As part of his rehabilitation Greg was reintroduced to sports, like swimming, and his condition began to improve.
The RAF Benevolent Fund supported Greg once again with funding towards his sport subscriptions meaning he could continue taking part in the sports which had has such a positive impact on his physical recovery.
Since then, Greg has represented Wales in disabled sports and the Special Olympics.
Now Greg has his sights set on an even bigger challenge.
On 9 April, Greg will begin his challenge to swim the equivalent of the English Channel at his local leisure centre. Greg will spend the next 12 weeks swimming three times a week, to complete the 21-mile feat.
Eileen said: "The RAF Benevolent Fund will always be there for Greg and this is his way of giving something back. Greg hopes fundraising for the charity will encourage others to follow suit and I would like to thank them on his behalf for everything they have done for our family."
