What it was like:
When riding in the bombardier's position the bomb release was regarded the same as a "non-pilot seat weapon system" and mapped to mouse initially, just like the guns in the turrets. This confused all of us and it was undocumented, so we were clicking on the actual buttons in the virtual cockpit to drop bombs.
When riding in the pilot's seat, the bomb release trigger set in the options worked normally.
How it works now:
Due to popular demand, since a couple of patches back the control scheme has been changed. Now it works the same way it used to work in IL2: pressing your bomb release key will drop bombs no matter if you are in the pilot's or bombardier's seat.
Just make sure you have the bomb bay doors open and also (mentioned before) that you can actually open the doors in case of mutli-crewing a plane online. All this might seem strange, but i like the way the intricacies of certain systems are modeled: if the lever to open the bay doors was on the pilot's console, the bombardier wouldn't be able to open them himself but would tell the pilot to do it.
In that sense, if i'm solo flying a bomber all controls are available to me. However, if i'm flying with a human crew online, each one has the controls available to his position.
Sure, all this does need to be documented at some point and corrected in some cases (the doors in the Blenheim were spring-loaded and opened under the weight of the bombs once they were released) but in the meantime i'm having fun decoding everything
