Aerospatiale AS316 Alouette III

Today hospital-based helicopter ambulance services all over the world save hundreds of lives every day, but in 1972, there was just one, and it was in Denver, Colorado.

At that time, emergency medical services were brand new. Using lessons learned during combat in Korea and Vietnam, hospitals were improving emergency room procedures and ambulance companies were hiring the first paramedics and emergency medical technicians.

Staff at St. Anthony Hospital in Denver had been working on using helicopters to transport severely-injured patients, but creating this complex emergency response system involved bringing together first responders, trauma surgeons, nurses, hospital staff, and government officials. Communication links had to be established, procedures created, and new technology developed. The hospital built a helipad on the roof, but the missing piece was a helicopter that could function well on hot days in Denver’s thin atmosphere.

The French Alouette III was perfect for the job. It was large enough for the pilot, two flight nurses, and two patients. Its powerful turbine engine gave it exceptional performance at high altitudes. Flight for Life used Alouette III helicopters from 1972 to 1992, replacing them with Aerospatiale AS350 aircraft that are still in use today.
