Have the pilot, co-pilot, nav, engineer and 4 engines on stools, tail & front gunner sat cross legged facing outwards, top gunner laid down firing upwards. All positions have a sound unique to them when in action - engines whirring, guns rasping, nav chattering on comms, etc. As previously mentioned, the narrator builds the story (all with the aid of sound effects from participants) this is the key to success. Generally the whole thing is a successful mission after bomb release and heading for home, until the engines splutter and die or catch fire, skirmishes with enemy fighters take place and handling problems occur (if you have multiple victims then a soaking for each goes down well). Eventually, not far from home, they need to bail out, but, the heroic front end stay and try to save a/c....needless to say mopping is required after. Ah, the memories....Enjoy.
