For what it's worth...
Our little coop group (HSFX) is flying a weekly B17 campaign with (on average up to 30 bombers) with humans flying the first couple of flights. The campaign is a tweaked version of the old Big Bird campaign by Jackstones and incorporates some of the C&C objects.
Each flight of the bombers has its own series of waypoints (i.e. the Target Set button hasn't been used to link up flights) but Jackstones went to the trouble of trying to time each flight so that they assemble over Felixstowe (Western Europe map). For the most part it works reasonably well with flights assembling at staggered altitudes. The overall formation is usually a bit strung out however distance-wise. What I've done is to decrease the speed of the AI bombers to 245kph in the .mis file as the 'default' is usually 300kph and once the AI got to altitude they would race ahead and us humans could not catch up. With the 245kph 'limiter' we (the humans) can catch up with the main body and actually have to throttle back sometimes to avoid racing ahead. It actually becomes a challenge to keep pace with the AI at all without dumping throttle etc. Level stabilizer becomes problematic when dumping throttles!
I could use the Target Set button for linking the bomber flights but I've found that if the lead flight gets taken out then 'Set' flights following suddenly seem to get stupid and their behaviour erratic.
There was a post a little while ago about a mod and head-on attacks in which one of the posters mentioned that the mod also had some sort of bomber formation mod. If there is such a mod can someone enlighten me as to a. what it does and b. is it worth trying.
thanks,
