Security precautions

Since September 11. security has become much tighter Many of the new precautions are dearly visible to passengers, with new rites as to what may be carried on board. Anything which could possibly be used as a weapon, even nail scissors, is strictly forbidden in the cabin. Much stricter controls are earned out on the identity of passengers, with authorities ready to use fingerprinting or biometric profiling as an extra security precaution. All baggage entering the hold is systematically screened for any signs of explosive materials, through the use of explosive detection machines. The assumption nowadays is that terrorists are not afraid to blow up an aircraft they are travelling on themselves. A rule is now in place banning liquids (except for very small quantities carried in transparent bags) on all flights to or from an EU airport. This measure was introduced lo prevent the possibility that liquids would be earned on board by different people and then mixed together to create an explosive device.

Anonymous armed air marshals operate on board aircraft in the US. While they existed prior to September 11. the US government was quick to recruit many more shortly afterwards and to declare their presence in order to deter terrorist attacks. When the British government considered I her use they were met with an angry reaction on the part of the British Airline Pilots Association who claimed that having any guns on board would be counterproductive. For one thing they feared the risks of the depressurization that a stray bullet might cause and they also pointed out that terrorists might fry to identify air marshals and seize their weapons.

Suspicious behavior is no longer tolerated (see Section 2). Any passenger who seems to be acting in a way that suggests to security personnel that they have something to hide will be prevented from boarding a flight, in almost all such cases the passenger turns out to be innocent, but no a*hne wants to take the risk of suspicious behavior once airborne as this would result in a costly diversion. Numerous cases of suspicious behavior which starts in the a* have likewise almost always had an innocent explanation, but the flight crew who choose to make a precautionary diversion are praised for their prudence.

Shoulder-launched missiles are considered to be a plausible threat to aircraft and this is why perimeter fencing patrols have been stepped up at airports. Military aircraft are routinely fitted with anti-missile defense systems and the same technology could be used on civilian aircraft as well, but it is expensive and for the moment there do not seem to be any plans to make this a standard feature.

Cockpit doors have been reinforced and are now locked during flight. No visitors lo the cockpit are allowed

The lessons of the past have led those responsible for the security of civil aviation to attempt to stay one step ahead of terrorists by predicting future threats and responding before these threats become a reality.
