BoB: Single Mission Help

[xin421]

It's too hard to pass.

There are 12 cargo plan to take care of, first wave of Bf109 is coming with almost 5 aircrafts, I ordered wingman to fight each of them 1 on 1 or ask wingman process the objective (Escorting). Either way I lose because they keep sending enemy aircrafts over again and again, and the 3rd wave is very sharp, I always only have 1 or 2 cargo plan left at that time.

It's too hard, I have been stuck there for 2 days.
