Is it a bird? Is it a plane? No, it’s dozens of brave souls abseiling down a Canary Wharf skyscraper to raise money for charity.

More than 150 people took a 230ft leap of faith down 20 Cabot Square this weekend in a mission for London’s Air Ambulance, based in Whitechapel.

Among the plucky fundraisers was 21-year-old Adam Gage, who was rescued by the team in an accident four years ago.

Adam suffered a severe head injury and was airlifted to the Royal London Hospital.

His mum Gill Gage said this week: “Without the London’s Air Ambulance it is unlikely that Adam would have recovered. We as a family and all his friends will be eternally grateful.”

Adam was joined by pal Nelson Metharam who grimaced as he took the plunge.

Also taking the plunge were employees from Santander, HSBC, Citigroup, United Insurance Brokers and Knight Frank.

Dr Gareth Davies, medical director and chair of the trustees, said: “Last year was a huge success, seeing abseilers raise �64,000 for the Charity. London’s Air Ambulance relies heavily on public donations and we would like to thank all the abseilers for their support.”
