Yes, it's something to do with Stutterfeeding air into the ignition chamber, but I can't remember the physics of it

I became out-of-date when they stopped using pitot-static systems to measure altitude etc

Hmmmmm... I'm going to post this in the Source Code section, I'll probs just get laughed at, but if they could create a modder-definable particle system (i.e. The modder defines the 'widget' bitmap and it's in-game size, the spew rate, velocity (For each axis), lifetime etc), not only could you use these for thrusters, you could also have something like a Waypoint object, which is the source of the particle emitter, possibly even set it's values in Fred as well
