BOMB SNIFFING ELEPHANTS???

——————————–
In the South African bush, elephants are being trained in the art of “bio-detection” to see if they can use their exceptional sense of smell to sniff out explosives, landmines and poachers. Supported by the US Army Research Office, the project looks promising.

During a recent test run, a 17-year-old male elephant named Chishuru walked past a row of buckets. A swab laced with TNT scent had been stapled to the bottom of one. Sticking his trunk into each bucket, Chishuru stopped and raised a front leg when he came across the one with the swab. He got the bucket right each time. And like a sniffer dog, he was rewarded with a treat: marula, a fruit that elephants love.

My question: How would they get those elephants to  work at the crowded airports in Paris, London and New York? As a guess, I would say the flight passengers in New York would feed them lots of peanuts to keep them happy.
