I have to put my hand up as an old pilot but not bold pilot.
Having flown across most of the world in my own light aircraft over 25 years I know when to say no.
Turning back is never easy.
I suspect a lot harder when you have pax in the back.
This was an old pilot/young sprog in conditions that you want to say no.
In my aircraft I say no.
Flying a bus or truck is a different matter.
Take a look at the Halifax MK accident. Cheap crew and pressure.
Corporate pressure is to blame here.
