Sure there is, one plane can de-ack and retake an otherwise already destroyed town. I did it myself a couple times this weekend at A199.... that map is still up, ain't it? 
I think a base could even be taken with 8 players max. 3 to cap base, 3 to whack town, 1 goon/m3 and one cover for goon/m3. I think there's a wish I haven't really seen - mission caps? Too many ways around it I suppose.
In any case, any base ops with more than 20 poepl... err lemmings... is way overkill imho. I see no sense of strategy (or tactics for that matter)... I can recall when there would be interdiction missions toward nearby bases (also prepping them for the next assault) and you would see goons getting better escorting (now I rarely see a goon properly escorted - merely flying under the lemming trail.) Neither do I really see buffs being escorted properly (if at all.)
What I now see more of, that makes me :oldrolleyes are two things I kind of
at:
1. So many "jabo" being run right off base at the closest enemy vehicle spawn
2. picking the aforementioned jabos, often in range of ack/gv fire
In the top ten most used (deaths + kills) vehicles... 6-7 are gv.
The game dynamic is shifting, and I think in a positive way, as HTC seems to be working towards separating the air/ground combat from the whack a mole it is now, to something more planes vs planes, gv/fps vs same, with planes going after them with somewhat less "clarity" - and accuracy (we're way too proficient at bombing, dive or level on small targets. low-level carpet bombing will become much more difficult, as well.) What would be helpful, would be newer maps where the airfield isn't so much a target unto itself, as opposed to some other target (town or factory or whatever) that isn't quite so close to the airfield. Toss in some of the "should also defend a capture" ideas and things look pretty interesting.
We'll see.
