OTTAWA – An internal review says screeners at the Edmonton airport failed to identify, intercept and handle a pipe **** in “the manner expected” by Canada’s air security authority.

The newly disclosed review says several personnel had feelings – with varying degrees of conviction – that the item might be a pipe **** or some other kind of improvised ********* device.

However, because of a manager’s assessment that the item was simply **** paraphernalia, no one acted fully on the suspicions, and the ****** were not called until several days later.

The Canadian Air Transport Security Authority’s review of the September 2013 episode, completed last ********, was obtained today by The Canadian Press under the Access to Information Act.

The review recommended improvements to training, search techniques, decision-making and clarity of employee roles.

Teenager Skylar Murphy, who had built the pipe **** with a friend for their own amusement, inadvertently left the device in a camera bag and forgot about it.

Murphy pleaded guilty last December to possession of an ********* device. He was sentenced to one year probation, fined $100 and ordered to make an in-person donation of $500 to the University of Alberta Hospital’s burn unit.
