The worrying thing about this incident is that had he chosen not to light a fire, he probably would have gone unnoticed during his airside sojourn.
He could then have planted a bomb, a gun, or heaven forbid a pair of nail clippers for an accomplice to retrieve and carry out his worst in the manicure department.
In the meantime, TRANSEC continue to fiddle while security burns. Walk through security in Glasgow airport and you may find a cheap polythene sword on display (alongside a selection of manicure and personal hygiene products) in a cheap plastic cabinet confiscated from a distressed 5yr old kid. Oh yes....and police preventing limo drivers from picking up crew at the pickup point because it's a car and not a bus and therefore not entitled to use that bus stop.
I reckon being a terrorist must be one of the easiest jobs in the world right now.
