The London Air Ambulance serves the 10 million people who live, work and travel within the M25 in their moment of greatest need. I'm one of those people and so are many of my family, friends and colleagues.

Please help me support the amazing life saving work they do in circumstances I can't even begin to imagine. In return, I'll abseil from the highest rooftop helipad in Europe which (I've literally just realised) is a free hang (no body contact with the wall!). Luckily I've read this only adds to the exhilaration of the event...
