Devon Air Ambulance Taking Off From Derriford Hospital

I was having a walk during my lunch break last November (2014) and happened to perfectly time walking past the Devon Air Ambulance ready to take off from Derriford Hospital. So I got my phone out and waited and filmed the lift off. You may not be able to tell much from the video, but I was struggling to stand at some points as the wind from the helicopter nearly blew me over!
