Sensors in windows among airport hotel's anti-terror measures

The full-length windows in the 563 hotel rooms of Crowne Plaza Changi Airport have sensors that alert security if the windows are being tampered with. For example, if someone tries to drill a hole in a window, perhaps to fire projectiles at the planes on the tarmac, the sensors will be activated.

These sensors, along with an enhanced emergency preparedness syllabus taught to all members of staff regardless of seniority, are among measures the hotel has introduced to meet an increased threat of terrorism, said security and risk manager Charlie Wong.
