Swenson’s glider was an exquisite instrument for detecting turbulence. A jumbo jet can weigh upward of half a million pounds and fly more than five hundred miles an hour. It charges through the air like an ocean liner, barely registering most winds. This glider wasn’t much heavier than a Harley and it was moving about as fast—fifty to seventy miles an hour. It felt every bump. Small aircraft account for many of the injuries caused by turbulence and, essentially, all of the deaths—about forty a year. They fly at the mercy of the wind.

For several years, switching to a window in a full screen space often does not necessarily focus the window. If you cmd+tab to a window that has its own full screen space, you can see that the window does not active, and that hitting a keyboard shortcut that is intended to be valid just gives you a beep. You have to manually click in the window to activate it. This especially affects Safari in full screen windows with video, where hitting space to pause or left/right to scan is no longer effective.
