The son of a former Trumpet farmer has carried out a wing-walk in his memory and plans to carry out a dare-devil task every year, around the date of his father's birthday.

Mark Bentham said the £5,000 he has already raised will go towards the John Bentham Trust, named after his father, to allow sufferers of motor neurone disease to benefit from revolutionary treatment on South Africa.

Mark, 32, from Fownhope, was strapped to the upper wing of an Utterly Butterly display team bi-plane on Friday, April 1, for a sponsored 15-minute whirl around the sky at RFC Rencomb near Cirencester.

He said: "It got a bit nippy towards the end! There were low-level fly pasts at 150mph and near vertical climbs and it did get a bit hairy.

"But a number of pals came along to support me and now I am looking for more dare-devil ideas."

These will take place annually, as close as possible to March 26, John Bentham's birthday.

One idea for 2006 is a climb of Mount Kilimanjaro in Africa, which Mark described as a "thrill". He is no stranger to risks, in March last year he took to a cage to view Great White sharks in their natural environment.

John Bentham, who was 67, was a former chairman of the Trumpet Agricultural Society and the first patient from the northern hemisphere to have ground-breaking treatment for motor neurone disease at the South African clinic.

This involved being given special medication through a drip and he soon started to show a considerable improvement. His unexpected death, on January 28, was down to a stroke and not related to motor neurone disease.
