OK, Melchior helped to debug this via chat while I was working on cell

It turns out to have been a pair of typos in fuel.nas that were
causing all the problems. What I *read* wasn't what the code was
actually doing, which explains all the confusion.
This one, though, is

To create smoke, we will need two things: smoke emitter and smoke object.
The smoke emitter will allow the user to set the following properties:
- X, Y, Z coordinate relative to the aircraft. This is the location at which
the smoke objects will be created.
- vector at which the smoke is emitted.

Of course you could do what I did with the

Never mind the last part. The code *does* correctly handle the boost
