That might well be so to prevent terrorists from smuggling bombs and weapons into planes. Amazingly though, airport security seems to have forgotten the departure area. I was at Heathrow airport just over a year ago during the start of the holiday season, and it was packed to the gills with travellers. If I am a would-be bomber, I would just cart some bags (I don’t expect security guards to check these) and explode them departures or the airline check-in areas. I mean, look at the picture above—how much PETN explosives can I pack into those bags? I can bring the whole terminal building down with that mother. I have seen this lack of security at departures and check-in areas in many large international airports, including our very own KLIA.
There is no need to hazard smuggling some puny device or matériel into an airplane to get a high body count.
