From Flintstone
Nobody explores the flight envelope
<cough!!> G4! <cough!>
Stunts are found in reputable airlines too. In established companies, it is very rarely a company culture but more an individual's own conception of his job. It should not be happening anywhere but in the real world it still does. It doesn't make it right though.
But the full quote in my post.
Nobody explores the flight enveloppe but if they do so willingly (other than cases of wake turb, windshear etc...), they do not belong in a modern professional environment, be with an airline (I am ex) or NJE.
