As you were flying multi crew jets (HS125) your co-pilot would have been looking out the whole time, which makes this rather different to doing it single-pilot.
Peter,
No-one has a higher opinion of your knowledge and experience than you do. Does it not occur to you that I know more about my biography than you do? I flew single crew piston twin air taxis for many years. I am not an idiot, even compared to you.
