I distinctly remember HiTech's stated dislike for mega-squads. With this setup, he now inadvertantly seems to have catered to the mega-hordes. 
You dont need a horde to take a base. These "hordes" are most of the time a bunch of pilots who know nothing of ACM and fighitng other planes....which leads to the norm...FHs being dropped or 10 planes vulching that 1 guy trying to up to defend while the other 10+ hit town.
Here is just an idea to cut down the number of planes needed to take a base....
2 sets of Heavy bombers...1 kills VH first pass then turns around toward town, the other hits town and kills most of it first pass. Continue passes till town is dropped once ord is all gone they can either rtb or drop low and use MGs to clean it up.
4-5 fighters with rockets....deack field/town kill dar and ord. Once out of rockets save Mgs for enemy planes or if needed use guns on town(shouldnt need much with 2 skilled buff pilots over head hitting it already.
1 C-47....all there really should be unless a 262 decides he wants to come buzzing in.
The cappers have of course the hardest job depending on who ups to defend said base. A bunch of skilless pilots upping is easier to kill then say SunsFan upping a K4 and JoeyTony upping a spit 9 together.
Maybe HTC has made it so you actually need to learn to fight to take a base hmmmm
