I don't mind B-17's that much but I always take in a gulp of air, hold my breath and resign myself to a possible death when I have to go up against B-26's (or Ki-67's for that matter).
Every time in my head I think (in a sighing voice)... OK... here we go.
Couldn't agree more Eagle. B-17s are easy enough to defeat it you strike from just slightly offset and above them in extremely harsh cutting vertical attacks. (aiming for wing roots) It may take a few passes and some -- god forbid -- patience...but you can take them down in most any bird pretty easily.
On the other hand, B-26s flame less easily, are significantly faster, (and therefore difficult to come in directly above, not somewhat behind) and are smaller targets. Only the faster birds in the game can maintain the speed necessary to make several slicing attacks from above within a reasonable amount of time. Sure you can hit from underneath, but with their speed you better be going a LOT faster than they are to avoid floating in their rear guns.
Back on topic -- bring on the A-26
