I took his question to mean that he wanted to watch the bombs from the time they were dropped until they hit the ground. EAW did this with bombs and it was a pretty neat feature.
Something I thought of recently was that since .trk files are just .mis files with some extra flight data I wondered if adding a camera to the .mis file after the fact might work or if it would corrupt the .trk files playback since they are touchy even without trying to edit anything? I haven't tried it yet because I keep forgetting about it.

I know it's not possible to edit .ntrk's in this manner.
