Fireball Forward - Air Support

[Dice Roller]

You don't hear much about Fireball Forward, but I like it.
I've never been that happy with the air support rules though - a random roll at the start of the game, apply any effects, and that's it.
I like the idea of ground attack aircraft models on the table. Yeah, I suppose you could put them on to show availability, but the whole air support thing is done before play even begins, so...what's the point.
I like the idea that aircraft may come in at other points in the game.

Anyone other FF players encountered this and have thoughts?
It could just be as simple as a company leader making an activation and if successful the aircraft appear on the leader's next activation and roll as written in the rules.

Thoughts?
