The answer to question #1 is No. Ground support missions do not count against an impulse's air activity limits.ORIGINAL: Dabrion
1. yes
2. yes
3. yes (only rebase missions let you stay face up)
4. yes (if this refers to the now disorganised bombers from 3.)
In general there is no discount for failed operations, you "pay" per attempt (which makes sense, since you have no hindsight until the mission is actually conducted).
I agree with the answers to the other 3 questions.
