Gung Ho Online Entertainment has released their dog fighting game called Silpheed to the Android Market. Its not free but costs a cheap $3.24 if you're interested and it sports great graphics, solid soundtrack, fast paced dogfighting style combat and also ship customisation options. Check out the video below which contains a short trailer and actual in-game gameplay:
There's also a free "lite" version available which was released months ago but for some reason it isn't compatible with my Nexus One nor my EEE Pad Transformer while the full version appears to be compatible.
