If your strafe missed that's your fault.
But historically innacurate? What are you talking about? In ww2 it was intensely difficult for planes to reliably hit moving ground targets. Far more difficult than this game suggests
There's plenty of gun-camera footage from WW2 that says otherwise. Gun-camera footage was reviewed after every mission and any pilot whose gun-camera footage showed him shooting empty ground while enemy units could be seen elsewhere would be grounded. If your CO saw footage of you continually shooting at nothing, you'd be stuck scrubbing toilets while all your buddies were off getting the glory.
My point is that, as long as strafes target a spot on the ground instead of enemy units, they are an unrealistic waste of munitions. No human behaves the way the stupid AI does when it comes to strafes. The difficulty of hitting the target should be addressed through the amount of damage done, not by making it nearly impossible to hit anything that can move.
What I'd like to see is the targeting from loiters applied to single pass strafes, that's all. I don't think that's unreasonable.
