The cockpits of all of our airplanes were really clean. It was a point of pride among the pilots to take 30 seconds when you got into an airplane to just wipe down their area. If everyone does that, they stay clean.

There is no such mentality in the US, where the cockpits of most airplanes are filthy. I find this unfortunate, to say the least.

As everyone knows, practically everything in Switzerland is clean. The airplanes are no exception.
