When we flew on Eldorado Nuclear DC-4s from Edmonton to Uranium City, I used to marvel at how the wings would flex in turbulence. It was always a bumpy ride at low altitude - the loaders would regularly carry empty ice cream buckets to passengers. There would be pallets of tri-milk ahead of passengers on the trip north, and pails of yellow cake on the trip south.
Oh, those good old days.
