Maybe we're illiterate. Maybe we're dumb. But we're having a hard time with this right now and it's annoying.

Just playing the original board game here and we don't really get aircraft attacking. So, here are some random  questions and clarifications for y'all.

1. Can infantry and tanks attack airplanes at all?
2. Can airplanes attack other airplanes?
3. Can airplanes defend a ground attack?

From what we can tell, it just seems kind of overpowered so we're not sure if we've got this right. Sorry for this completely noobish question, but we're trying to teach it to ourselves here ^^;;
