While we were out in the boat with Debbie & Craig this afternoon a water bomber made a low level pass over Henan Point head and then circled around to pick up a load in the bay in front of out cottage. Very shortly another plane came in and made another pickup run. It seemed like there were two planes making loops of about 5-8 minutes to fight a fire in the area. They made perhaps 5-6 passes and then they were gone.
In each pass the plane picks up 6137 litres (1621 US gallons) of water in 12 seconds! The full specs and capabilities can be seen on the Bombardier CL415 site. A great video of the CL415 fighting fires in Northern Ontario is here, and another video of forest fire fighting air traffic control with multiple planes can be found here.
UPDATE: A reliable local source told me they were bombing a fire at the intersection of the Jones Road and the railroad line. Apparently, a train triggered a small fire which was quickly contained.
