Absolutely beautiful plane. Reverse thrust was powerful enough that it was common to see them roll backwards slightly on the runway after landing. Eisenhower's presidential transport was one of these. The gear was so tall that they could fit an underbelly cargo hold to the outside of the aircraft I remember a video of propeller balancing for one of these aircraft. It's massive, something like a 10-12 foot diameter, variable pitch blades. Using a buffing wheel, they polish the blades until they balance perfectly and placing a matchbook on one of the blades is enough weight to start them rotating.
