wording: qualified to comment is not the same as qualified in actively taking part of aviation, but any comment could of course influence the PIC's decisions. A bit generalised but from my experience Glasgow cops are certainly not shy, rather the opposite. The ones I got to know don't deal precisely according rules and regs as Glasgow isn't really a rule and regs culture and place (as most places down in Englandshire..), perhaps more a who shouts the loudest environment. David Trail didn't seem to be like that though.
