Covenant et al.... Perhaps the guy in the original thread should have mentioned simply that the door was open. That might have cued the CA into following KAC procedures and keep the cockpit door closed and LOCKED at all times while pax are on board.
This person may, indeed, have just been making a statement of fact " Oh, golly, the cockpit door's open, I could hijack the captain now!", but I'm glad this young lady had the presence of mind to bring it up to the Captain (even if she couldn't read this guy's comments as 'helpful')
BTW, chaps, what does "IMHO" mean????? & remember, there are no silly questions!!!
