Fighter jets escorted a diverted London-to-Washington, D.C., flight to Boston's Logan airport Wednesday after a distraught passenger pulled out a screw driver, matches, Vaseline and a note referencing al-Qaida, an airport spokesman said.
United Flight 923 landed safely, Logan airport spokesman Phil Orlandella said.
The flight, with 182 passengers and 12 crew members landed safely, UAL Corp. spokesman Brandon Borrman said. Borrman said a female passenger was spotted engaging in some "suspicious" activity, but he could not immediately say what the activity was.
State Police and federal agents met took control of the plane after it landed.
Passengers were seen coming off the plane on the tarmac and being loaded onto a bus. Orlandella said their carry-on luggage was being checked.
The flight from London's Heathrow Airport was scheduled to land at Dulles International Airport outside Washington, Transportation Security Administration spokeswoman Amy von Walter said. According to Von Walter, the fighter jets launched and trailed the flight out of an abundance of caution.
Last week, British authorities said they foiled a terror plot to blow up trans-Atlantic flights from London to the United States.
