Canadian authorities are investigating the case of an teenager who was apparently allowed to board a flight evn after security found a pipe bomb in his carryon. Using gunpowder obtained from an undisclosed source, 18-year-old Skylar Murphy of Spruce Grove, Alberta, Canada and buddy made two pipe bombs. Boys being boys with explosives, they detonated one in a field. Saving the other for later, Murphy stuffed the 15-centimeter by five-centimeter tube, with its three-meter fuse, into a camera bag and ostensibly forgot about it until he was carrying the camera bag and bomb through security at the Edmonton, Alberta Airport. An alert Canadian Air Transport Security Authority (CATSA) guard found the bomb. Being polite, he tried to return the explosive device to Murphy. According to CBC News Edmonton, Murphy declined the offer and told the guard to keep it. Murphy then joined his family on their flight to Mexico for a vacation.
