THE PROBLEM OF airport security has again been in the spotlight this week, with Dublin Airport coming in for criticism over apparent “deficiencies” in its systems.
It’s not the first time that the world of scanners and searches has hit headlines.
After an apparent plot to blow up transatlantic flights using liquid explosives was uncovered in 2006, most liquids and gels were banned from aircraft. Since then the stakes have been raised with an underwear bomber – and even suggestions that explosives could be carried inside the body.
It all suggests an ongoing battle between global security operations, and those who are out to thwart them. So what does the future of passenger flight hold? TheJournal.ie set out to find out.
Why aeroplanes? How did airport security come to be the front line in the so-called ‘war on terror’?
The reason, paradoxically, is partially because of our own fear. The cultural status that air disasters hold, and the huge media coverage that they generate, make planes an appealing target for anyone looking to get the world’s attention.
“The thing about the aviation industry, is that it gets you on the front pages,” says aviation expert Dr Frankie O’Connell of Cranfield University. “If a small plane crashes in Bangladesh, it makes the news here. It’s a very global industry. People are thinking “What if I was on that flight?”
There’s also an economic motive. Air travel is key to the worlds of business and politics, and any disruption causes serious ripples. “It’s a prime purpose of terror organisations to hurt nations economically,” says air security expert Dr Richard Bloom at Embry-Riddle Aeronautical University in Prescott, Arizona. “Hurting commercial aviation does that.”
Well, plenty – or so it seems. As well as the well-publicised full-body scanners – which reportedly began undergoing trials at Dublin Airport last year – there are a number of other innovative ideas that aim to improve detection of dangerous items (and people):

Well, it might improve matters slightly – but unfortunately there will always be loopholes, says Bloom. “The problem, is whatever screening technology you’re using, it will be more successful against some things and less against others.”
And it’s not too difficult to get information about this. ”It’s relatively easy to learn the parameters of technology, and to try and take advantage of them.”
Profiling – the kind of detection used by the so-called ‘checkpoint of the future’, where behavioural cues and other information is used to identify a threat – also has its problems. “Even with the best kinds of profiling the error rate is quite high,” says Bloom.
This is especially problematic when it comes to false positives; people who just happen to fit the profile of a ‘threat’. When too many people get hauled off for interrogation too many times – or strip-searched, or worse – the system starts to break down.
In short, no. “Most security experts would agree that the very idea of having perfect security is not possible,” Bloom says. “Whichever method you’re using there will always be a certain error rate.”
Some hope that any terrorists will essentially give up and turn their attention elsewhere. “These guys will keep coming up with innovative stuff,” O’Connell says. ”But the aviation world has put up a lot of barriers against it. So I think they will probably move on to other areas, like ferries and cruise liners.”
What this means in practice is that the experience of air travel, with all its attendant frustrations, isn’t going to change. There will still be queues, and we’ll in all likelihood still have to unpack bits of our bags.
And here’s the thing: even if terrorism went away entirely, we couldn’t go back to the days when you could just stroll onto a Stratocruiser and be handed a champagne cocktail. This, says Bloom, is because the whole aviation industry has changed almost beyond recognition.
Airlines’ costs, especially fuel, have risen dramatically and they are under more pressure than ever before. As a consequence there are fewer flights, and they’re more often full. “Unless someone comes up with a new economic model,” Bloom says, or “a new way to fuel an aircraft” – we’re in for more of the same, for the foreseeable future.
Sorry about that, everyone.
A lot. There are “vast” resources being poured into protecting air travel, says Bloom. But here’s the thing: most of it we don’t even see. The pesky bag scanner and (maybe) pat-down search that we go through at the terminal is just the tip of an iceberg, the bulk of which extends far beyond the airport building.
Bloom breaks it down into four key focuses – only one of which most of us are aware of:
