dtx's devious tactic for bombing GVs:
1. Get a decent LW plane w/500kg(s) and WGr21s - 110, 190F8.
2. Climb to about 3000 feet above GVs. Roll inverted.
3. In level, inverted flight, get the enemy to the center of your "up" view.
4. Cut throttle and pull down vertically.
5. Release 500kg at ~1000 feet.
6. Pull the hell out.
