Man wandered off plane and past security

The modern phenomenon of walking like a zombie, transfixed by your smartphone/tablet, usually at worst causes you to walk into a lamppost, but on Saturday morning in Sydney it caused an airport to be evacuated.

A passenger exiting a plan was so engrossed by his iPad that he wandered past security and out into Terminal 3, causing an alert to be sounded after he was spotted on CCTV and the evacuation of everyone in the terminal.

"The man disembarked a flight and left. It appears he wasn't paying attention, was looking at his iPad, forgot something and walked back past (the security area)," a Qantas spokeswoman told The Sydney Morning Herald.

"He has departed now."

Passengers were rescreened and let back in following the man's absent-minded amble, with the delay only lasting about an hour.

The incident highlights not only our obsession with technology, but also how alarmingly easy it must be to bypass security at Sydney Airport.
