I think you are confused...my understanding is that heading is the
direction you are pointing, course ( = vector, i guess) is the direction
you are moving.

I'll answer this with the proviso that I may be corrected by any REAL aero-
dynamicists(SP?) out there....

Airplanes run into this problem because they must change COURSE to target an
enemy ship.  Since they only have a limited ability to change heading w/o
changing course, in atmosphere they are essentially the same thing.  Take any
airplane, mount small maneuvering jets in strategic places (nose, tail, wing
tips...) and put it in space and you separate the two.  You can now do things
that any self-respecting plane in atmosphere can't (move in direction A while
pointing in direction B)

You change heading with the manuevering jets, and course with the main engine
(if heading <> course).  The problem in atmosphere is that high-G turns put
the plane at the outer rim of a circle.  Since the linear speed is constant,
a smaller circle places a higher G-force on the plane/pilot.  Too much stress
on either the plane's structure or the pilot's and things start to fall apart.

Take a spaceship, change it's COURSE as fast as you change the plane's and
you will place an equivalent stress on it's structure.  The limiting factor
becomes how much stress the ship's/occupant's structure can take.  That's what
inertial dampers were invented for.

Question:  putting inertial dampers on an airplane should allow you to make
higher-G turns.  The limiting factor here becomes max linear speed (remember
frictional heating) + max rotational speed (which depends on elevator
deflection and moment arms and other things I don't want to think about).
True or not?

Again, HEADING <> COURSE.

How big is the leak?  How much fuel is left in the tank?  These things will
all affect how fast the fuel will be lost.  Unless the leak approaches a
significant fraction of the tank size or there isn't much fuel left in the
tank, it won't be lost immediately.
