I uploaded several very simple staged missions for bombing practice. They all start with smfld for small field and you take off from a field on auto takeoff and then warp to a point near a small enemy airfield. Either heavy fighter or B17 or B24. There are a total of 3 or 4 friendly planes and 4 enemy planes. They work best if you use a custom arena which is very simple to set up. There are no briefings to minimize the mission time. It only takes about 2 minutes to be in the air 10000 feet over your target ready to drop and then repeat. Go to the Staged Mission Forum to get the full instructions I posted on running the missions and custom arenas.
