Its such a shame I can't take my little boy to visit the flight deck in flight. I used to be glazed over with wonder for days after visits when I was in my teens. Even as an adult PPL I nearly always asked to visit, and once got invited back for a jump seat view of the approach and landing...(AirUK

). On a 744 flight to LAX once I was up front for a good 20mins while the Captain explained, and demonstrated amongst other things, how nicely the 747 responded to control inputs. My colleague was squirming with embarrasment when I asked the stewardess if I could visit!
Its seems such an injustice that today's generation are denied this wonderful insight.
Obviously things have changed
Anyway, my question which I expect has been asked before, does anyone believe the policy of locked flightdeck door is likely to thaw over the next few years?...and do flightcrews think its a proportional precaution to the risk/threat?
If you were ferrying an aircraft for example, and there were no other PAX apart from maybe a relative (is this allowed? guess not so academic question in reality?) would you be okay to let them sit in the jump seat?
Look forward to your views...
