Washington (AP) - Despite the ease with which an alleged terrorist got an explosive aboard a Detroit-bound flight, the Obama administration says the incident shows the U.S. aviation security system worked.
Billions of dollars have been spent on aviation security since the Sept. 11, 2001, terrorist attacks, when commercial airliners were hijacked and used as weapons.
Much of that money has gone toward training and equipment that some security experts say could have detected the explosive device the 23-year-old Nigerian man is believed to have hidden on his body on a flight from Amsterdam to Detroit.
"One thing I'd like to point out is that the system worked," Homeland Security Secretary Janet Napolitano said Sunday morning on CNN.
"This was one individual, literally, of thousands that fly and thousands of flights every year," Napolitano said. "And he was stopped before any damage could be done."
Investigators are piecing together Umar Farouk Abdulmutallab's brazen attempt to bring down Northwest Airlines Flight 253 on Dec. 25. Law enforcement officials say he tucked below his waist a small bag holding his potentially deadly concoction of liquid and powder explosive material.
Harold Demuren, the head of the Nigerian Civil Aviation Authority, says Abdulmutallab's ticket came from a KLM office in Accra, Ghana. Demuren said Monday that Abdulmutallab bought the $2,831 round-trip ticket from Lagos, Nigeria, to Detroit via Amsterdam on Dec. 16.
Demuren declined to comment about Abdulmutallab's travels in the days before he boarded his Dec. 24 flight from Lagos to Detroit via Amsterdam, saying FBI agents and Nigerian officials view the information as "sensitive." He says Abdulmutallab checked into his flight with only a small carryon bag.
Abdulmutallab had been placed in a U.S. database of people suspected of terrorist ties in November, but there was not enough information about his activity that would place him on a watch list that could have kept him from flying.
Officials said he came to the attention of U.S. intelligence last month when his father, Alhaji Umar Mutallab, a prominent Nigerian banker, reported to the American Embassy in Nigeria about his son's increasingly extremist religious views.
In a statement released Monday morning, Abdulmutallab's family in Nigeria said that after his "disappearance and stoppage of communications while schooling abroad," his father reached out to Nigerian security agencies two months ago. The statement says the father then approached foreign security agencies for "their assistance to find and return him home."
The family says: "It was while we were waiting for the outcome of their investigation that we arose to the shocking news of that day."
The statement did not offer any specifics on where Abdulmutallab had been.
Abdulmutallab's success in smuggling and partially igniting the material on Friday's flight prompted the Obama administration to promise a sweeping review of aviation security, even as the Homeland Security secretary defended the current system.
White House spokesman Robert Gibbs said the government will investigate its systems for placing suspicious travelers on watch lists and for detecting explosives before passengers board flights.
Both lines of defense were breached in an improbable series of events Christmas Day that spanned three continents and culminated in a struggle and fire aboard a Northwest jet shortly before its safe landing in Detroit. Law enforcement officials believed the suspect tried to ignite a two-part concoction of the high explosive PETN and possibly a glycol-based liquid explosive, setting off popping, smoke and some fire but no deadly detonation.
Airport security "failed in every respect," Rep. Peter King of New York, the top Republican on the House Homeland Security Committee, said Sunday on CBS' "Face the Nation." "It's not reassuring when the secretary of Homeland Security says the system worked."
An apparent malfunction in a device designed to detonate the PETN may have been all that saved the 278 passengers and the crew aboard Northwest Flight 253. No undercover air marshal was on board and passengers and crew subdued the suspect when he tried to set off the explosion. He succeeded only in starting a fire on himself.
Security experts said airport "puffer" machines that blow air on a passenger to collect and analyze residues would probably have detected the powder, as would bomb-sniffing dogs or a hands-on search using a swab. Most passengers in airports only go through magnetometers, which detect metal rather than explosives.
Abdulmutallab was treated for burns and was released Sunday to a prison 50 miles outside of Detroit.
Stiffer boarding measures have met passengers at gates since Friday and authorities warned travelers to expect extra delays returning home from holidays.
Adding to the airborne jitters, authorities detained a man, also from Nigeria, who locked himself in the bathroom on Sunday's Northwest flight 253 from Amsterdam as it was about to land in Detroit. Investigators concluded he posed no threat. Despite the government's decision after the attempted Friday attack to mobilize more air marshals, none was on the Sunday flight from Amsterdam, according to a government report obtained by The Associated Press.
