That was movie but similar thing happened in Newark International airport.
Newark International went on high alert on Sunday, with huge delays for passengers, after an unidentified man was spotted in the "sterile" zone. He was not caught or even identified.
The Star-Ledger daily quoted security officials saying that videotape reveals the feared intruder was no more than a man wanting a last kiss from a departing woman.
He simply passed under a rope barrier and with the woman went "hand in hand toward the boarding area", the newspaper quotes the security officials and US Senator Frank Lautenberg as saying.
