I propose that the aircraft suffer the damage that being caught in a nuclear radius does to ground units. As it is, the damage is severely mitigated, even when the landed aircraft (but not convoyed) are targeted.

Examples: Attacking with level 2 nuclear bombers
A city with one infantry, and 4 nuclear bombers (level 1).
The first strike destroys the infantry and one bomber. No damage reported on structures.

The second strike does a little more damage, reducing the bomber stack health from 99% down to 81%, and slight damage to a nuclear reactor.
Morale damage to the province itself reduced it to from 100% to 20%.

Now, I'm not saying that everything should have been wiped out in the first strike, but I was of the opinion that more damage should have been done to the province upgrades.

What do you guys think? Constructive criticism is what's looked for here.

I don't know, I get the feeling that the grounded aircraft were soaking damage meant for the province, so it may be a look into the how the damage mechanics are working, more than buffing or debuffing any units
