This is G-EHMS, a MD 902 Explorer that has been the London Air Ambulance since 2000. The twin engined helicopter has permission to land anywhere to assist with serious medical emergencies. Here it has landed at a cordoned-off road junction. It can get specialist paramedics and doctors to the people who need them, and then transport the casualty to hospital at up to 140 kts.
