I was the “Landing Officer” (aka Ground Contact) for a medical helicopter from Colorado’s Careflight of the Rockies yesterday — I’m a volunteer medic for Ouray County EMS.
While I can’t discuss the medical reasons for having the chopper respond, that a chopper did land is obviously public knowledge.
I had a radio to talk directly to the pilot in one hand, and my phone in “camera” mode in the other, to get several photos and a short video, which are all cut together in this <1 minute clip:
Careflight 3 is a Eurocopter AStar B3, and has a crew of three: a flight nurse, a paramedic, and a pilot. It can carry one patient.
The Careflight choppers are designed to operate in high-altitude environments (very handy for Colorado!), and cruise at an air speed of 245 kph (132 knots, 152 mph). Interestingly, the crew has night vision goggles so they can operate at night.
Originally designated the Eurocopter AS350 Écureuil (Squirrel), it is a single-engine light utility helicopter originally designed and manufactured in France by Aérospatiale and Eurocopter, now Airbus Helicopters. In North America, the AS350 is marketed as the AStar.
