Mercy Flight -- Film Description:
"Saskatchewan's air-ambulance service serves the scattered population on prairie farms, northern bush camps, Indian reserves and mining settlements. A project conceived by an ex-pilot of the Royal Canadian Air Force, it was an immediate success, making twenty-nine flights in twenty-one days. This film looks at its organization and operation."
