RAM operates a Cessna 206 aircraft from a permanent base at Lethem on the southern border of Guyana near the Brazil border. Airplanes of this type have been operating continuously from its Lethem base since February 17th 2001. Flying doctors, dentists, nurses and veterinarians are all flown to remote Amerindian villages to provide care and emergency supplies. The aircraft is called out for some type of medical or humanitarian relief flight on an average of once every 2.2 days throughout the year. Fuel for the airplane has to be trucked in by 4X4 trucks hundreds of miles along muddy dirt roads and dangerous bridges. The current price of fuel delivered to Lethem is over $5 US per gallon.
