Breathe in, breathe out. Like most nervous flyers, you struggle to stay calm while you catapult upward and out east over the Atlantic as your flight gains altitude. Enjoy a cigarette and settle down now that the no-smoking sign is off. The attendant will be here soon to serve you a stiff drink which you can sip while you gaze out the window at that huge wing and wonder how anything as large as this can ever fly. What if we run into a storm? Are storms really getting worse? How much pollution is this thing spewing out? You wonder how many internet surfers have these same questions as you sip and try not to think too much about it, but your mind can’t dive into any rabbit hole that does not bring you out thinking about how you rely on the state of things outside of this thin aluminum tube. “Fill me in on atmospheric science,” you ponder.
