Cockpit or Cockup?
I do not think flying with your door open is such a big deal atleast it should not be made into one. Follow your company procedures on that.
When it comes to cockpit visits for the flying public, well, I think that those will return once this paranoia settles a bit. With all this hysteria around this is not likely to happen any time soon. Is flying with the door open pathetic and a simply an ego-trip for pilots trying to prove something. I think not. Canīt be that simple, otherwise world would be black and white.
