Whilst most of you will say there is nothing wrong with this incident, it does prove that there is one rule for the wealthy and another for the rest of us.
No, what it proves is how stupid Dft rules are in not allowing the Captain the discretion as to who and when to allow anyone on the flightdeck.
Before all these banal security rules we used to have people such as air traffic controllers, firemen and even spouses, sons and daughters to visit the flightdeck - notice that the Daily Mail article states these rules only apply to UK registered a/c and/or those in UK airspace. Notwithstanding that individual airlines/states may have their own rules this is not the case universally.
