A Boeing B747-400 that has been converted to an aerial firefighting tanker is ready to enter service this week, Global SuperTanker Services has announced. The airplane, christened Spirit of John Muir, will be based in Colorado Springs, Colorado. From there, it can be deployed at speeds up to 600 mph to reach wildfires almost anywhere in the continental U.S. within 4.5 hours, or anywhere worldwide within 20 hours.
