Security breach at Sydney Airport A SECURITY breach at Sydney Domestic Airport stopped flights this evening while investigators reviewed CCTV footage. A passenger left a secure area at Qantas Terminal 3, which caused all flights at the airport to be put on hold. The man was gone for about ten minutes and when he returned he informed airport staff he had gone to the bathroom. Security officers made the decision to stop flights while CCTV footage was reviewed to ensure the passenger had not come in contact with any other people. The delay lasted ten minutes and now flights are back on schedule, according to a Qantas spokesperson. Angry jetsetters immediately vented their frustrations on Twitter, saying a "moron" had run through a security check. "Security alert at Sydney airport - no way in and no flights out, aaaarrggh," Twitter user @CBAWomenInFocus said. A Moron has run through security. Terminal being emptied. Stuck on board," @sdipietr, said.
