Corporal Lee Benson and Senior Aircraftman Sam Bradshaw both work in Simulator Support Flight at the Defence College of Air and Space Operations at RAF Shawbury and had originally planned to complete 24 hours.
However, with friends, family and colleagues offering support and encouragement, they decided to double the size of the challenge to 48 hours.
Both men, who completed it in style, have very strong reasons to raise funds for the Brain Tumour Charity, the largest dedicated funder of research into brain tumours globally.
Lee said: "This is a cause that is very close to our hearts. I dedicated the challenge to Sergeant Steven Vout, a long-standing and much respected member of the RAF’s Trade Group 9 Flight Operations Assistant trade. He sadly died last month after a two-year long battle with brain cancer. Steven remained strong throughout, inspiring family and friends with regular updates of his battle with the terrible illness.”
Sam dedicated it to his father, Robin Bradshaw, who has been battling the life-changing illness for five years. He said that although his father's life has been flipped upside down his positive attitude has not let the cancer get the better of him.
The duo set a target of raising £1,000 and they have currently raised £1,145.
"If you would like to show your support please visit justgiving.com/team/DCASO," Sam said.
A charity spokesman said: "We are committed to saving and improving lives, they are moving further, faster to help every single person affected by a brain tumour. We are set on finding new treatments, offering the highest level of support, and driving urgent change.
"And we are doing right now, because we understand that when you, or someone you love, is diagnosed with a brain tumour a cure really can't wait."
