Fly

Before, McCoy was terrified of flying. The thought of flinging yourself forward into uncharted territory, the idea that one minute you could be safe in the ground and the next in the vastness of space, where there were no roads laid out, no tracks to follow, no handy escape route for when the pilot screwed up and you needed to run – it terrified him.

And then Jim Kirk happened.

Now, McCoy is not afraid of flying.

Now he's only scared of crashing.
