There are arguments to support both sides of the use of canines. But to date, despite the best efforts of many talented scientists and technicians, there is no

AVIATION SECURITY TECHNOLOGY SYMPOSIUM

Even those with a vested interest in the technology say dogs are better under many circumstances.
​"A dog's nose is probably the most sensitive piece of equipment going.

Police Department's counter terrorism unit

Dogs, with their exquisitely sensitive noses, have been trained in recent years to pick up the scent of explosives on people moving through crowded concourses, and so far they have proved a better early warning system than anything human engineers have come up with.
​"They outperform both men and machines," said James Waters, chief of the New York City Police Department's counterterrorism unit, which just this week graduated its latest squad of dogs capable of following the vapor from explosives such as the terrorist bomb-making material of the moment, TATP, used in the Brussels and Paris suicide explosives.
