Yeah, I'm kinda surprised it keeps getting resurrected.
The "Dive Bombing Heavies" IS a dead issue, Kermit and Krusty. First, HT doesnt think its a problem at all. Second, there arent any available solutions that would work. The F6 solution would make absolutely no difference, since with full salvo you can hit f6 and drop ord in about 3/4 sec.
Requiring level drops is both unrealistic -- see the detailed angle tables, based on the position of the bomb in the rack -- and (in HT's words) arbitrary.
HT has said he plans to eventually implement modelling for bomb bay structures, with realistic physics for drops and inertia. That will involve a fair amount of coading, I'd bet, and it will require a limited reworking of the friendly collision model (since bombs are now technically friendly objects and thus cannot collide with part of a friendly aircraft, so you cant damage your plane by releasing too steeply).
I could concieve of this being done as part of CT, but if it isnt done there, I dont expect it to be high on the priority list for a good while.
So, it isnt impossible that it wont be left undone for an infinitely unlimited time, but no way to be sure.
