Most of us are familiar with the idiom “six degrees of separation.”
The theory, based on a 1929 short story, supposes that we are all connected by a chain of five other people. Essentially, it’s the small world philosophy. Airplanes make the world even smaller. Such was the case on a day that my flying coincided with a friend that lives miles away. In addition, it was the same day in January that an Alaska Airlines 737 Max 9 lost a door plug in the fuselage, providing a harrowing experience for both passengers and crew.
