You don’t simply board a plane.
You walk
ride a subway
escalator
elevator
airport shuttle train
more elevators, escalators,
go down hallways.
More elevators, escalators ,
stairs
walkways
to the line to get on the plane.
You walk into a tube and wait.
You find your seat
you wonder if this flight is still a good idea at this point.
Hours later, you land.
It’s a miracle.
