Yesterday I had the pleasure of going through airport security twice for the same flight. I’d left something in the car. Later in the day, while waiting for a connection in another airport, I walked past an even busier security checkpoint, people rushing to lace up their shoes, stuff toiletries in bags, zip laptops into cases.

That flying is an exhausting, dehumanizing experience is news to no one. But you forget just how exhausting and dehumanizing when most of your trips are by car.

In exchange for the miracle of flight, we have the humiliation of full-body scans, the inconvenience of unpacking what we just packed and stuffing it into gray bins, the thrill of padding barefoot along the airport floor.

A reminder that even though we soar through clouds, our fears and troubles usually keep us earthbound.
