No Leezyet, they didn't send boys in posing as pilots. They boarded as passengers, started slashing the throats of passengers and cabin crew until the pilots let them into the cockpit.
The documentaries that I have watched on Discovery etc. claimed that at least one of them went through security dressed as a passenger then once through put on a crew jacket thus posing as flight crew to be able to gain access to the f/deck.
You ladies and gents that fly the a/c have rules and regs that you have to adhere to and so do those pieces of cr@p that are just there to hassle you and give you grief but are usless in reality as many of you claim. Many of you wouldn't dream of breaking those rules and regs and they don't either as you and they risk loosing their jobs and nobody wants that.
You all chose to work in the industry so have to accept that security screening is a major part of it, so rather than hassling those low paid chaps on the screening points, why not just go with the flow and get on with it, it actually takes more time to argue with them than it would to go with the flow. If you don't agree with something, then don't take things with you that might cause a problem - Do you really need nail clippers - why not cut them at home before you go, or why not write to the authorities and put your point forward rather then taking it out on the people who cannot do anything about it.
