Britton Coulson, left, and Wayne Coulson stand in front of one of 10 former Royal Canadian Air Force CC-130H Hercules aircraft recently acquired by Coulson Aviation from the Government of Canada. At right is a Coulson C-130H outfitted for aerial firefighting with the company’s proprietary RADS-XXL retardant delivery system, capable of carrying up to 4,000 U.S. gallons, or more than 15,000 litres, of water or fire retardant. The acquisition doubles Coulson’s global C-130H fleet to 20 aircraft, expanding its capacity to build the world’s largest C-130 airtanker fleet.
