I used dfang's instructions for depressing the bombsight in the cockpit.ini file for use in level bomb runs. Using a canberra b2 I,ve found the method very effective. So long as you stay at the same speed and altitude using the same ordinance you can more or less work out the depression angle for the gun sight, toggling the cockpit off for the bomb run. Only problem is that the camberra is a very stable and steady bombing platform, so It will take a lot of work to adapt it to the f-100 so I can use it in the campaign.
On a similar note to the idea about dive toss, the ability to manually enter the depression setting for the air to ground gunsight during the game would be a great improvement and would be far easier to implement than "proper" air to ground fire control. Also, pilots in the 50s and early 60s would have had fully depressable gunsights for bombing and access to data regarding release parameters for different mil settings......
guess I'm just getting sick of having to exit the game and edit the cockpit.ini everytime I want to bomb from a different altitude....
