Ok... I can understand some of those checks helping. Most of which were done, as far as media reported.
Though the flight would probably still be there now, whilst the arguments about surrendering hand baggage/valuables raged on...
And fully agree with banning all cigs matches/lighters on all flights. And make smokers travel naked, because their clothes stink too!
And even if the flight was cancelled, or discontinued, the perpetrators would just hop on the next flight, whatever the airline.... hopefully yours FBW, so you could cancel it, and go back to hotel for a beer!
Cheers
