I'd like to suggest that you get rid of the three components, that asteroids are made of. At the moment they don't matter at all and once you start mixing armies, it's impossible to keep track of anyway.
Instead you should give each asteroid one power that effects only the swarm that is currently present.
For example, you could have defensive asteroids where the defending swarm is twice as strong as usual or asteroids that spawn new fighters twice as fast. Associate each type with a symbol or something else that is easily recognizable, so it is easy to distinguish between the types in the heat of the battle, when you're zoomed out.
It would really make the game more strategically.

The game won't start!
I get a "Network failure " when I try to launch it. I guess it's because it's trying to download the highscores but can't connect! I'm behind a proxy!

Thanks for the altitude trick. I got another plane that just reached 77527, but isn't as fast on the way down. It is very easy to land, because it loses all of its speed when it enters the atmosphere. The name is 'Battlefield 194'

The plane 'fireworks' can do a 2.2 space race but is impossible to land and 'fireworks2' has very short take-offs.

Hah, guess you found the bug that makes some planes able to fly forever. I forgot about this whole conservation-of-energy law of physics.

Yeah, I got one of those too:
Air Time: Beat2  761 m 45 s
Distance: Beat2  582.3 miles
 

this is fun.  I like going for the records.  Wish there was something to compare mine to though.

Here are my current records for you to beat
Widest Loop: 2044 feet
Number of Loops: 105
Altitude: 7717 feet
Air Speed: 582.5 knots
Air Time: 36 m 16 s
Distance: 20.8 miles
Shortest Take-Off: 51.8 feet
Space Race: 2.8 s
G-Force: 21.6 Gs
Heaviest Looper: 4032 lbs

Also, it crashed firefox every time I tried to refresh the page, so replaying it was pretty obnoxious.

I think I got that too, once.

Got that too, but figured out that you can restart it by pressing R

"Fast" is as fast as the name suggests and "Gandalf" isn't bad either!
Nice game
