Better looking jet exhaust.
Testing terrain generation again, cleanup.
Minor graphic fixes.
Can now enter and exit aircraft.
Bring fog in when transitioning through top cloud layer to hide terrain scaling.
Test.
Make aircraft be at ground level initially.
Meh graphics.
Better camera trailing of aircraft.
Better aerodynamics simulation.
More tweaks.
Go back to old fog cloud transition method, this looks better.
Don't add glide if aircraft is traveling too fast.
Render foliage and buildings in one pass, should be faster.
Tweaking terrain generation, again...
