I'm abseiling down the 100ft drop at Belfast's iconic Castle to raise vital funds for Air Ambulance NI. The charity Air Ambulance NI works in partnership with the Northern Ireland Ambulance Service to provide the Helicopter Emergency Medical Service (HEMS). The service delivers urgent pre-hospital care directly to people who are critically ill or injured on average twice per day. The life-saving service requires £5,500 each day in fundraising, so public donations are crucial. Any money you raise will help to save lives, brains and limbs!
