On my last evening in Montana, we visited the Ravalli County Airport where helicopters fighting the Moose Creek Fire were returning at day’s end. This Skycrane heavy-lift helicopter, which sucks up massive amounts of water from lakes and drops it on wildfires, came in while we were there. I looked up the tail number, which is closer to the nose on this aircraft, and discovered that it is more than 50 years old. Glad it’s still serving.
