Are planned airport scanners just a scam?

New technology that Gordon Brown relies on for his response to the  
ChristmasDay bomb attack has been tested - and found wanting
The explosive device smuggled in the clothing of the Detroit bomb  
suspect would not have been detected by body-scanners set to be  
introduced in British airports, an expert on the technology warned  
last night.

The claim severely undermines Gordon Brown's focus on hi-tech scanners  
for airline passengers as part of his review into airport security  
after the attempted attack on Flight 253 on Christmas Day.

The Independent on Sunday has also heard authoritative claims that  
officials at the Department for Transport (DfT) and the Home Office  
have already tested the scanners and were not persuaded that they  
would work comprehensively against terrorist threats to aviation.

The claims triggered concern that the Prime Minister is over-playing  
the benefits of such scanners to give the impression he is taking  
tough action on terrorism.

And experts in the US said airport "pat-downs" - a method used in  
hundreds of airports worldwide - were ineffective and would not have  
stopped the suspect boarding the plane.

Umar Farouk Abdulmutallab, 23, allegedly concealed in his underpants a  
package containing nearly 3oz of the chemical powder PETN  
(pentaerythritol tetranitrate). He also carried a syringe containing a  
liquid accelerant to detonate the explosive.

Since the attack was foiled, body-scanners, using "millimetre-wave"  
technology and revealing a naked image of a passenger, have been  
touted as a solution to the problem of detecting explosive devices  
that are not picked up by traditional metal detectors - such as those  
containing liquids, chemicals or plastic explosive.

But Ben Wallace, the Conservative MP, who was formerly involved in a  
project by a leading British defence research firm to develop the  
scanners for airport use, said trials had shown that such low-density  
materials went undetected.

Tests by scientists in the team at Qinetiq, which Mr Wallace advised  
before he became an MP in 2005, showed the millimetre-wave scanners  
picked up shrapnel and heavy wax and metal, but plastic, chemicals and  
liquids were missed.

If a material is low density, such as powder, liquid or thin plastic -  
as well as the passenger's clothing - the millimetre waves pass  
through and the object is not shown on screen. High- density material  
such as metal knives, guns and dense plastic such as C4 explosive  
reflect the millimetre waves and leave an image of the object.

Mr Wallace said: "Gordon Brown is grasping at headlines if he thinks  
buying a couple of scanners will make us safer. It is too little, too  
late. Under his leadership, he starved the defence research budget  
that could have funded a comprehensive solution while at the same time  
he has weakened our border security.

"Scanners cannot provide a comprehensive solution on their own. We  
must now start to ask if national security demands the use of  
profiling."

Mr Wallace added that X-ray scanners were also unlikely to have  
detected the Christmas Day bomb.

The Government is looking at millimetre-wave scanners for widespread  
use in British airports as part of Mr Brown's review. They are safer  
to use than X-ray scanners because they do not emit radiation and do  
not require passengers' consent. Pregnant women cannot go through X- 
ray scanners but there are no such health risks with millimetre-wave  
technology.

However, a Whitehall source revealed that the DfT and the Home Office  
had already tested both the millimetre-wave and X-ray body-scanners as  
part of an ongoing assessment of airport security and anti- terror  
measures.

But the security scare has caused national governments and airports to  
renew their interest in body-scanners. Amsterdam's Schiphol airport,  
where Abdulmutallab changed flights en route from Nigeria to Detroit,  
is to activate 17 scanners it bought two years ago for flights to the  
US, despite EU advice that there are privacy and human rights issues.

Last week the US Transportation Security Administration ordered $165m- 
worth of scanners, using both millimetre and X-ray technology, from  
L-3 Communications.

Qinetiq had developed a similar millimetre-wave body scanner, but is  
now developing a sophisticated "stand-off" scanner which does not pose  
any privacy issues as it does not show a body image. Materials hidden  
on a body reflect back signals, showing up as a red alert on screen.  
Kevin Murphy, product manager for physical security at Qinetiq,  
admitted this SPO system would also not have picked up the Christmas  
Day bomb, but insisted that it could be used as part of a "layered  
approach" to security in mass transportation, which would also include  
monitoring people's behaviour.

Mr Murphy echoed Mr Wallace's doubts over whether the millimetre-wave  
body scanners being discussed by the Government would have picked up  
Abdulmutallab's hidden explosive. He said: "It is conjecture whether  
or not these methods would have seen through clothing. I don't think  
anyone knows."

He added: "The solution is to acknowledge that there isn't a single  
technology out there that is an answer to the whole problem."

Each full body-scanner costs around £100,000. However, opinion is  
divided among aviation experts. Writing in The Independent on Sunday,  
Chris Yates, Aviation Security Editor of Jane's Information Group,  
says: "Body scanning (whether it be millimetre-wave or X-ray based and  
manufactured by any of the companies in this sector), has a  
significant role to play in enhancing UK airport security immediately.

"Body scanning is only half the story, though. The Government cannot  
ignore the liquid aspect any more. Liquid explosive became a high- 
agenda issue following the thwarted transatlantic bomb plot of 2006  
and is clearly implicated in the attempted downing of Northwest  
Airlines Flight 253. If the Government skirts over this aspect it will  
be nothing short of a dereliction of duty."

On Friday, in an announcement on the Downing Street website, the Prime  
Minister said an urgent review of security at UK airports would be  
implemented.

Promising to react quickly to the "wake-up" call of last week's  
attempted atrocity, Mr Brown added: "In co-operation with President  
Obama and the Americans, we will examine a range of new techniques to  
enhance airport security systems beyond the traditional measures.  
These could include advancing our use of explosive trace technology,  
full body scanners and advanced X-ray technology."

A spokesman for BAA, which owns six UK airports, including Heathrow,  
said on Friday: "Any comprehensive review of airport security should  
involve government and the aviation industry, and should establish how  
a combination of technology, intelligence and the profiling of  
passengers can build a better defence against the unpredictable and  
changing threat from international terrorism."

Responding to Mr Wallace's claims, a DfT spokesman said: "Body- 
scanners are being assessed urgently as part of a package of measures  
to respond to the latest incident. Trials of body-scanners have  
already taken place and these are being assessed urgently as part of  
an immediate review of airport security."

In the US, the "pat-down" search used by security staff was derided as  
ineffective - because officials are forbidden from frisking sensitive  
areas. Analyst Michael Boyd said: "To have people hold up their arms  
and just pat them - like I'm really going to carry a bomb down there.  
You know where you're going to put it, and no one's going to go there."

Mr Brown has also convened a meeting for 28 January on the terror  
threat posed by Yemen, where Abdulmutallab is alleged to have  
undergone terrorist training.

In a fresh announcement yesterday, Downing Street announced an  
emergency cabinet committee meeting with senior ministers and  
intelligence chiefs to discuss the UK's response to the attempted  
attack.

No 10 and the White House have agreed to step up efforts to tackle the  
emerging threat from Yemen and Somalia.
