Tanker 12 once again, this time at Whitecourt, Alberta, [CYZU], warming up those great-sounding, old, round engines before a test flight. Anyone who has heard the big Pratt and Whitney R-2800 Twin Wasp running up close will never forget that ground-shaking rumble or the clouds of blue smoke on start-up. It's the sweetest, dirty sound you'll ever hear. You can tell you are playing with horsepower, all 2000 of them (each side).
