Another thought just came to mind...
Instead of having Formation Pilots type '.detach' in the text buffer to separate from the Bomb Group, have a hot key for detachment. For example, hitting the num pad 'minus' key 2 times in quick succession would detach you from the group.
This would be important in the event that the Group Leader is battered so badly in his sole remaining aircraft that he loses control of it and perhaps starts to spiral down in flames. Since he's not yet dead he would drag the tethered formations of the remaining planes down with him, making it all but impossible for the remaining formations to quickly regain control and continue to the target and successfully strike it as a formation. After all, when a Group Leader in World War II was knocked out of action, other planes of the squadron didn't follow him down. Therefore, a means to allow for a quick disconnect needs to be made available in such an event.
Using this feature, when the Group Leader informs the pilots that he is going down or the Formation Pilots see his demise, they could quickly detach and retain control of their aircraft and continue on the bomb run.
Equally important, if the Group Leader were to hit the num pad 'minus' key 2 times in quick succession he would detach all planes that had been attached to him. This would be the proper course of action for the Group Leader to take if he had to break formation due to damage or was unable to continue accurately to the target, not unlike what happened during the war when lead bombers had to limp back home short of target acquisition due to enemy damage, mechanical breakdown, etc.
Anyway, Group Leaders, in addition to Formation Pilots need this ability in the event that VOX goes down and his condition can't be relayed to the other pilots. The Group Leader, knowing he is mortally damaged or unable to effectively command the group, could detach the formations from him and then bail from his aircraft ... or change course and travel alone.
Anything else I'm missing?
Why am I still up thinking about this idea? >>
