Take off collision detection.

[git-project-one]

Hello,

Some better in game explanation of collision detection would be great. For instance if I set two plans to take off from two parallel runways (in opposite directions) you get -4. However runways should be able to be used simultaneously

Example 18L and 36L in the debug airport.

The problem here is that you lose score for tailwind takeoffs, which would happen in that airport with 18L/R takeoffs. I'll add a feature so that it prints out what you did wrong when you lose score. In real life, they almost always have only one runway for takeoffs.

Cool, thanks.
