Reminds me of one of the many words of wisdom in this game "You should fly at night a lot, or not at all".
If the moon is out you can see surprisingly well. If it's dark out there you are pretty much trusting to fate. Kinetic energy is a function of velocity squared, so keep as slow as you safely can. If you hit something, hope it is made of a material that causes the forces to be managable by your flesh and blood. You can survive quite a few g if you do it right.
