Here is the list of las vegas cheap airfare wiki pages: near Denver in 1955 by a bomb placed in a suitcase by a passenger�s son, who wanted to collect on her flight insurance policy that named him as the beneficiary. Numerous other First World aircraft have been destroyed by bombs, including a US domestic jet from Chicago to San Diego, a Swiss jet from Zurich to Tel Aviv, a British jet from Athens to Nicosia and a US jet from Athens to Rome. Even though the events of 9/11 had nothing to do with the baggage compartment, efforts to prevent an explosion there increased drastically after that tragedy. The methods in place now in the First World include: � Explosion detection equipment: Various technologies are employed to identify the ele- ments of a bomb. Explosives detection is now routine for passenger luggage, and is to be extended to air freight in the near future (e.g., by 2009 in the USA). Some machines use CAT scan techniques that provide colored images of objects that could contain explosive compounds. Other devices seek traces of explosives, or evidence of wiring or other materials that could trigger an explosion.

The people performing the searches often do not know exactly which objects might pose dangers. In one instance, a bomb was built into the lining of a suitcase, with a thickness no greater than wax paper. Disaster was avoided because of the extraordinary security skills of El Al, but a similar success might not have occurred under different circumstances. � Positive passenger bag match: Under this policy, a bag will not travel in the baggage compartment of an aircraft unless it is accompanied by a passenger who is known to have boarded the aircraft. In a full implementation, a bag is removed from the aircraft if the passenger who
