Passing by the Chrysler lagoon

A fat pigeon?

When I first noticed that it made me think about how exhibitors needed to stock spare parts to fix things like this during the Fair. I imagine it was a constant challenge to keep the place in good shape.

This made me think about the challenge to keep mechanical things adjusted properly, even when they had not broken. The fascinating ball-bearing bouncer at SKF always had a few in the bottom of the display case that didn't make it through to the exit port - due to accumulation of dirt and grease, I'd guess.

Much later, at EPCOT, the back-stage tour showed us the 3-D hydraulic stage changer for the American Adventure pavilion. I wondered how stable all the tolerances were. Think of how many times you have seen elevator doors working, but not smoothly. This also brings to mind that, at the time of the fair, cars did not have electronic engine controls doing a continuous automatic tune-up the way they do now, and things needed to be adjusted every so often.

I remember those anomalous SKF ball bearings well! Used to watch and watch hoping to see how the failures occurred. My first experience with quantum flakiness.
