Guns, knives and explosives don't always have common shapes or sizes. Some are designed to slip detection, and airport screeners must be vigilant.
So when staffers using an X-ray scan at Berlin's Schönefeld Airport couldn't identify a mechanical device in a bag on Tuesday morning, they called police and shut down the D Terminal due to "suspicious content in a luggage piece," the federal police said, according to CNN.
The bomb squad arrived, and an announcement went out over the loudspeaker: Can the gentleman with the multiple unknown objects in his luggage please step forward and explain them?
He was shy, CNN reported. And reluctant to talk, only calling the items "technical stuff." He was not identified by media reports.
Meanwhile, a bomb squad probed the luggage. It made its determination in an hour.
