What do you actually enjoy about flying?
There is not much that you can enjoy about flying, you're in an enclosed space, with not much room to move around. I do not hate flying, it is just a boring experience.
How does the thought of falling not scare you?
After all the flights that there have been, how many do you think have just 'fallen' from the sky? That's right, none.
What do you like about being high in the sky, despite the fact that humans historically have spent most of their time on the ground?
As I said before, there is not much to like, it is faster than going in a car/coach etc, still takes quite a long time depending on where you're going. Humans spending most time on the ground... hmmm. Where else are we going to be?
