Simple Dropable Object Mission

OK, I have "fooled around" with the mission SDK a bit, and for some reason things just aren't clicking for me. Maybe somebody here can point me in the right direction...I would like to create a very simple mission that allows the user to load 6 flour bombs on any plane at the beginning of the mission at Nellis AFB. That's it...just load some flour bombs so the user can go drop them on targets like Air Force practice bombs (the ones that just leave a smoke puff where they land). Can somebody point me in the right direction to accomplish this? Thanks in advance!
