The Shock Trauma Air Rescue Society (STARS) was formed in Calgary, Alberta to provide emergency medical care and transport to the critically ill and injured. Since 1985, more than 23,000 missions have been carried out.

Over the years, the STARS fleet has grown from a single helicopter to seven Eurocopter BK117s, serving eastern British Columbia, Alberta, Saskatchewan and Manitoba from bases in Calgary, Edmonton, Grande Prairie, Regina, Saskatoon and Winnipeg. Each helicopter covers a 250 km radius and can hold one critical patient, or two non-critical. The operating range can be extended further than 250 km when refueling is available.

The STARS crew consists of a critical care nurse, an advanced life support paramedic, and two pilots. Emergency referral physicians also fly with the crew on approximately 20 per cent of responses, and are available for telephone consultation during every mission.

Recently, the organization has been preparing for the arrival of three advanced technology helicopters that will fly faster, further and have the capacity to transport and care for two critically ill or injured patients. The new AgustaWestland AW139 helicopters are scheduled for service in Edmonton, Calgary and Saskatoon.

STARS is equipped with night vision goggles, enhancing night rescue capabilities.

The STARS vision of saving lives through partnership, innovation and leadership is supported by four pillars: Emergency Medical Communications, Patient Care & Transport, Education & Research and Fundraising & Community Partnerships.

I was thrilled to be able to talk to one of the pilots just after the landing...I asked a lot of questions and got a lot of answers... What an in-site. Alberta is so lucky have such a fine team...
