well... there are a number of things that the bombers in AH do, or rather "can do" that they didn't in WWII.
First, the typical level bombing speed in AH is far greater than in WWII. B24's and B17's typically dropped at less than 220 TAS. In AH, it is full throttle and why not??? There is no accuracy penalty for high speeds. I can not vouch for the B29 or the Mossi B Mk XVI. I can show you hand written records from my grandfather's flight logs on where, alt, speeds, etc for B24D bombing runs in the south PTO.
Second, there is no altitude or angle restriction for when a bomber is able to let loose their ordnance. Now obviously there are some aircraft that were designed, built, and utilized in both dive bombing/shallow dive bombing and level bombing. The B5N, Ju88, B25, and even the supposedly the Lancaster (although I can not find actual literature to show it was designed to dive or shallow bomb), were all dual purpose. There must be some latitude in labeling bombers if ever there were any restrictions placed on which model could drop bombs outside of the bomb sight.
There are a couple more, but those two are the biggest issues I have with the bombers in AH: there are no restrictions. Use them as dog fighters, spawn point carpet bombers (from 500ft), etc etc There is nothing stopping the use of an aircraft far outside the realm of what it truly was capable doing.
FWIW: the Head On pass takes TWO, it **always** takes 2 to "HO". It is a viable tactic and an inevitable tactic as well. With the goal being to get your guns on the enemy, sooner or later each pilot will be aiming as well a being targeted at the same time. If you choose to partake in the Mexican stand off then be prepared to get shot down and consider yourself very lucky if you manage to stay in the air. Once you accept that fact the sooner you will stop crying about it and deal with it.
