It is a known fact that AA will miss a number of planes unless you set the plane to AA ratio such that none will be missed - Then sadly NONE will be missed.
AA versus aircraft is never a match - its a deterence for aircrafts or a mismatch in AAs favor; never in-between.
And how long will this battle be? 5 minutes - Because the premise does not permit it to last over a long period of time, unless the pilots are intentionally dicking around
Which is ALL pointless eitherway, since it is based on too many What-ifs.
Yeah but they can make a few passes... or you make the target really small so it's quite hard to hit it, especially under AA fire... and it can also me made so you have to bomb it a few times... There are lots of balancing options... But the question remains, is it worth it? There certainly aren't many historical scenarios where it can be used...
If anyone has played Operation Big Week for FH1 he will know what I am talking about... Axis get Komets and ME 262 and Allies cardboard B-17s, Mosquitos, and Thunderbolts that fly like bricks, and a few P-51s. They have to destroy 3 factories and a U-boat pen under really heavy AA fire... But still it CAN be done! And Axis can easily win it too, just by keeping enemy B-17s at bay.
