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.
