Well the gameplay is oke, the controls look good !!
I like that the joystick is moving along in the direction your flying ^^
But the movement controls can get better, I have the feeling some times that when your flying at high speed, I don't get the feeling that I'm really flying at a high speed.The only moment I feel that I'm really going at high speed is when you first take off with your fighter in to orbit.
One thing you need to add is AI, I don't see any attacks or space ships who are trying to attack you but as you already said, it's a bug
The fighter from the outside looks nicely modeled but the skin is abit the problem, it looks pixelized

That's the result when you use MD2 mapping where your mesh is to small and your texture is to large. Btw which skin size are you using ??
The fighter from the inside looks creative, some tv screens giving you information, two voices who are giving some information, very usefull and creative

The textures from your world have the same story, they look to clean have no perspective

This can be easily sovled when you follow some advance texturing and skinning tutorials.
The terrains would look fine if the textures come out more and when they give it some fun to look at.
What I did like much was your aiming, the laser beams are always being nicely traced into the middle of your crosshair. The bombs you drop are good but their explosion effects can get better, again it can get way better following nice tutorails where they explain advance particals. Also your explosion are simple sprites some the effect is abit low but oke

And one more thing, some time I've seen some lack on the FPS but not much. Maybe try and include a LOD system.
beside all my C&C, the game in overall looks quite nice.I'm sure it will be improved

Keep it up !!!!
Cheers
