While many people look for a quiet life as they reach their 70s, Jenny Holland has different ideas.
In less than two weeks the intrepid septuagenarian is due to take part in a daring 'wing walk' to raise funds for the Norfolk and Norwich University Hospital charity.
Ms Holland, who is afraid of heights, will stand on the top wing of a 1940 Boeing Stearman Biplane and flown around at speeds of up to 135mph.
The trip, which is taking off from Damyns Aerodrome in Upminster, Essex, on July 23 will involve a variety of flypasts and manoeuvres, including a terrifying drop dive of 500ft.
Ms Holland, 70, from Toftwood, Dereham, said: 'I feel like if I just imagine myself somewhere lovely and sunny I can forget the fact that I'm absolutely terrified of heights!'
The wing walk is Ms Holland's way of saying thank you for the care she has received at the NNUH eye clinic.
She has been a patient there for nine years.
Ms Holland said: 'I have been psyching myself up over the past few months, and can't believe the big day is just around the corner.
'It's a daunting challenge but it's all for a fantastic cause.
'The eye clinic, specifically Mr Glenn, has been amazing to me over the years and I just wanted to say thank you and to give something back to the trust.'
So far, Ms Holland has raised £10,000 but is still looking for more people to get behind her fantastic fund-raising efforts.
She said: 'I'm determined to raise enough money for a special operating chair for intravitreal injection patients at the NNUH eye clinic, which costs £12,000. Any support would be truly appreciated.'
Andy Glenn, consultant in ophthalmology at NNUH, said: 'We are overwhelmed with Jenny's support to the unit.
'She has already completed the London Marathon and a parachute jump for us but this is definitely her biggest challenge to date.
'We are so pleased to have inspired this support to the charity.'
