Ok guys.... I think we really should drop the topic on airport security here as it can get a little sensitive by nature. Furthermore, one experience may differ with another but no one to mediate with a real info on what's going on at the airport. For the record, there are x-ray machines outside the gate hold rooms in the transit area for a reason. The fact: there are x-ray screening being done upon arrival in SG. Whether your flight will be affected by it or not, nobody knows.
