They set off the alarms twice but still managed to get through with the box cutters. About a year later as I flew through LAX I was ushered into the special security check line to have all of my luggage checked. It was so disorganized that security completely missed searching a massive suitcase that I had taped shut. As mad as I was to be searched (and blacklisted) I was horrified to think of how easy it was to get anything through the security team. I sure hope it's been improved by now.
The video shows hijackers Khalid al-Mihdhar and Majed Moqed, each dressed conservatively in slacks and collared shirts, setting off metal detectors as they pass through security around 7:18 a.m. Moqed set off a second alarm, and a screener manually checked him with a handheld metal detector.
Nawaf and his brother, each wearing slacks and Oxford shirts, were directed to a nearby counter, where they appeared to closely examine their tickets while another screener checked Nawaf's carryon bag with an explosive trace detector. Each was cleared to board Flight 77.
