We had the Eisenhower centenial here in Abilene Ks. a few years ago. Eisenhower's presidential plane, the Columbine, was brought in for the festivities. It was a beautiful Connie that had been restored just prior to this event. They flew it in and out of the Abilene airport many times, at night, and during the day. The sights and sounds brought back memories to me of the times when my father had flown out of KC in one, on his many flights to Georga. He was sales manager for Clipper Saw Co. at the time. I really loved the night flights, where the "blue flames" were very visible.
I got a tour of the plane by the crew, and learned that this particular Connie had belonged to a crop duster in Canada, along with many others. The owner was looking through some history of the Connie in I believe the Smithsonian, where they had all of the serial numbers of all the Connies that had been built. He came accross the Eisenhower plane, and realized that he owned it, and they had been cabaging parts off of it to keep some of the rest of the fleet going. To make a long story short, they restored it to its original glory, and flew it to Abilene.
There is also a Connie sitting on the tarmac at Salina Ks., about 25 miles from Abilene, that has been there for years. There have been many stories about that one, and I heard it was flown out once, but had to return has it had some problems.
One other thing on the Eisenhower plane, was that they did not have the exhaust collector rings on two of the engines, and instead, just had the little stub pipes on each cyl.. Made for a beautiful display of "blue flame" at night.
