" Given the amount of tracking of aircraft life-hours, cycles-it seems odd for aviation expert Edmund S. Greenslet (AW&ST May 19 p19) to generalize and apply the "dog years" standard to airliners, in this case multiplying calendar years by three to get an idea on life stage. Venerable DC-3s and B-52s are 150 -180 years old, according to his standard, and are dead by most biological standards. As any of us past Greenslet's "prime of life" standard of 36 can tell you, it's not the years that tell the story. It's the mileage and maintenance."
