Pornographic videos may have revealed more than just, well, what they usually do. A series of videos filmed in Phoenix, Arizona's Sky Harbor airport may demonstrate a serious security problem for the airport.

"We are in a heightened level of security. If they can't detect this, which took several minutes, what would happen if it were something more serious," Phoenix City Councilman Sal DiCiccio told ABC News' Phoenix affiliate KNXV.

An investigation by KNXV found at least seven videos of women exposing themselves, engaging in oral sex and intercourse while apparently avoiding the detection of airport security officials. Furthermore, the videos appeared on professionally run websites and the women were paid.

Approximately 200,000 people pass through the airport each day.

One video follows a woman from baggage claim, into an elevator and to the top of a parking garage overlooking the tarmac. She then flashes her breasts and says, "Hello, Arizona" before performing sex acts on the man behind the camera.

Julie Rodriguez, spokeswoman for Sky Harbor International Airport, told ABCNews.com in a statement that Phoenix Police are "reviewing the facts regarding the websites that you are referring to."

"Such a large public area can be tempting for people involved in this type of activity," she said, "so the airport urges customers to always be aware of their surroundings and report any form of suspicious activity."
