On December 22, 2001—just months after the 9/11 attacks—Richard Reid boarded American Airlines Flight 63 from Paris to Miami with homemade bombs hidden in his shoes.
During the flight, Reid tried to detonate his shoes, but he struggled to light the fuse. Crew members and passengers noticed and restrained him.
The plane diverted to Logan International Airport in Boston, and Massachusetts State Police officers took Reid into custody. Reid told FBI agents that he made the shoes himself.
This is the pair of shoes [Richard] Reid—also known as the “shoe bomber”—tried to detonate. FBI bomb techs determined that the shoes contained about 10 ounces of explosive material.
They also do it by religion apparently. There was a video on Youtube of a Canadian Jewish girl who turned Muslim that recounts the difference of how it went at the airport. Apparently they put a sticker on your passport and if the number starts with a 6 you get extra scrutiny.
