I love flying at night.
True, flying in the day has its advantages(seeing other aircraft from the air for example), but at night, it seems smoother, and I tend to feel like I am really going somewhere far. I like to look down and see the city lights, and depending on what route I am flying, I can usually take an educated guess at the city with all the lights. Plus, you don't have the ever blinding sun going in through the window.
Give me a break, I created this username when I was a kid...
