CHARLOTTE, N.C. – A new recipe for explosives on planes linked to al Qaeda has prompted the Department of Homeland Security to increase security at a number of U.S. Airports including Charlotte-Douglas International.
A magazine linked to al Qaeda in Yemen called "Inspire," published instructions for making explosive devices.
The recipe is said to be an improvement over what was used in the so-called underwear bomb that failed to detonate on a flight to Detroit on Christmas Day in 2009.
The new security measures will include re-checking random passengers even after they have been cleared through security checkpoints.
There will also be more pat downs and hand swabbings to test for explosive residue.
Passengers at Charlotte-Douglas said they understood the need for new, tighter security.
"Addressing the threat is absolutely practical. It's what you'd expect and what you'd hope for," said Erich VanRavenswaay as he waited to board a flight.
Another passenger, Henry Webb said, "I was actually in New York for 9/11, so I guess I don't worry that much about it."
