Great video!
I have a little hint for you on the bombers.. aim for the middle of the wing, not the fuselage and come down on them at about a 30degree attack angle.
I was able to cut off the wings from 3 bombers in ATAG last night in 1 sortie and 2 in another and still have some ammo left for defence when heading back to base!
