G, all of B-Ns work is now based around military/ (can't remember the number) but I think it is annex 2 (government aircraft on civil register), so they have no requirement for a civil qualified pilot with engineering experience (especially one only holding a fATPL).
You are quite right BAE, Dorneir, Airbus would not be able to offer any opportunities to our colleague, well BAE are now only involved in military airframes, Airbus (small to medium sized airliners) so unless our colleague here has 1000's of hours on the Airbus airliners I don't think sales demo flying is going to be a possibility there.
