"It was so easy — a lot of us were surprised it hadn't happened sooner," says Jeff Price, who was assistant security director at Denver International Airport on Sept. 11, 2001, and is now an aviation security expert at Metropolitan State University of Denver.

Airport security at that time was carried out by private contractors, usually hired by the airlines, with few federal standards. Those security contracts usually went to the lowest bidder.

"Before 9/11, security was almost invisible, and it was really designed to be that way," Price says. "It was designed to be something in the background that really wasn't that noticeable and definitely did not interfere with aircraft or airport operations."

"You could walk up to the gate at the very last minute. You did not have to have a boarding pass," Price says. "All you had to do was go through the security checkpoint — no questions asked, no ID needed."

That forever changed on Tuesday, Sept. 11, 2001.

Now, travelers often stand in long lines at security checkpoints with wait times that can exceed an hour. We take off our shoes, empty our pockets and take laptops and other devices out of carry-on bags before stepping into high-resolution, full-body scanners, while our bags go through 3D-imaging X-ray machines. And don't forget to take your liquids of 3.4 ounces or less out of your carry-on.
