The plane takes off and levels out when the handler says to the first man,
“Watch this” He tells the dog, “Rover, search!”. The dog jumps down, walks

along the aisle and sits next to a woman for a few seconds, it then
returns to its seat and puts one paw on the handler’s arm.He says “Good
boy,” turns to the first man and says, “That woman is in possession of

marijuana, so I’m making a note of this, and the seat number, for the
police who will apprehend her on arrival.
“Fantastic!” replies the first man.

Once again he sends the dog to search the aisles. The dog sniffs about,
sits down beside a man for a few seconds, returns to its seat and places
both paws on the handler’s arm. He says “Good boy”, and turns to the first
man and says, “That man is carrying cocaine, so again, I’m making a note

of this, and the seat number. ‘That’s marvellous, I never seen anything like it!” says the first man.

Once again he sends the dog to search the aisles. He goes up and down the
plane and after a while sits down next to someone, then comes racing back,
jumps up onto the seat and shits all over the place. The first man is
surprised and disgusted by this, and asks “What the bloody hell is going
on?” The handler replies “He’s just found a bomb.”
