Or operate for the military which is exempt

The military aren't exactly exempt, they can however elect to be their own design authority for a 'mature' type. Where they get to decide what mature means, I believe that's how they got the Jaguar upgrade done without paying BAe the gross national debt.
The MoD have their own airworthiness system which I can only see getting stricter post the Nimrod crash/inquest/verdict.

Nice pictures.

Must look much bigger than what it shows in the pictures?

Well.. yes and no AD. That aircraft is a 400srs (a 419) and they're not that big when compared to something with 'intercontinental' .. wide-bodied size. If one ran into you.. you'd know about it but in the grand scale of things, 1-11 400's are pretty dinky.. let's say small but perfectly formed

A Global Express BizJet is slightly longer and a bit more span but not so fat

It's sort of Viscount size....closest US is the DC 9 10/15 series.

Certainly a much nicer looking aircraft compared to some of these modern bizjets.

Many moons ago, as a nipper, I used to look at 1-11's at Manchester and yawn, in much the same way I look at A320s today.

They were common and no one got excited at seeing them as they were part of the furniture.

Now I would probably sell one of my organs to see one.

Funny how things change over time.
