It consisted of an El Al security agent quizzing Ann-Marie Doreen Murphy, a 32-year-old recent arrival in London from Sallynoggin, Ireland.
While working as a chambermaid at the Hilton Hotel on Park Lane, Murphy met Nizar al-Hindawi, a far-leftist Palestinian who impregnated her. After instructing her to "get rid of the thing," he abruptly changed his tune and insisted on immediate marriage in "the Holy Land".
He also insisted on their travelling separately.
Murphy, later described by the prosecutor as a "simple, unsophisticated Irish lass and a Catholic," accepted unquestioningly Hindawi's arrangements for her to fly to Israel on El Al on April 17.
She also accepted a wheeled suitcase with a false bottom containing nearly 2kg of Semtex, a powerful plastic explosive, and she agreed to be coached by him to answer questions posed by airport security.
"What is the purpose of your trip to Israel?" Recalling Hindawi's instructions, Murphy answered, "For a vacation."
"Are you married, Miss Murphy?" "No."
"Travelling alone?" "Yes."
"Is this your first trip abroad?" "Yes."
"Do you have relatives in Israel?" "No."
"Are you going to meet someone in Israel?" "No.
"Has your vacation been planned for a long time?" "No."
"Where will you stay while you're in Israel?" "The Tel Aviv Hilton."
"How much money do you have with you?" "Fifty pounds." The Hilton at that time costing at least pound stg. 70 a night, he asked:
"Do you have a credit card?" "Oh, yes," she replied, showing him an ID for cashing cheques.
That did it, and the agent sent her bag for additional inspection, where the bombing apparatus was discovered.
Had El Al followed the usual Western security procedures, 375 lives would surely have been lost somewhere over Austria.
The bombing plot came to light, in other words, through a non-technical intervention, relying on conversation, perception, common sense, and (yes) profiling.
The agent focused on the passenger, not the weaponry. Israeli counter-terrorism takes passengers' identities into account; accordingly, Arabs endure an especially tough inspection.
"In Israel, security comes first," David Harris of the American Jewish Committee explains.
Obvious as this sounds, over-confidence, political correctness, and legal liability render such an approach impossible anywhere else in the West.
In the US, for example, one month after 9/11, the Department of Transportation issued guidelines forbidding its personnel from generalising "about the propensity of members of any racial, ethnic, religious, or national origin group to engage in unlawful activity." (Wear a hijab, I semi-jokingly advise women wanting to avoid secondary screening at airport security.)
Worse yet, consider the panicky Mickey-Mouse and embarrassing steps the US Transportation Security Administration implemented hours after the Detroit bombing attempt: no crew announcements "concerning flight path or position over cities or landmarks," and disabling all passenger communications services. During a flight's final hour, passengers may not stand up, access carry-on baggage, nor "have any blankets, pillows, or personal belongings on the lap".
Some crews went yet further, keeping cabin lights on throughout the night while turning off the in-flight entertainment, prohibiting all electronic devices, and, during the final hour, requiring passengers to keep hands visible and neither eat nor drink.
Things got so bad, the Associated Press reports, "A demand by one flight attendant that no one could read anything elicited gasps of disbelief and howls of laughter."
Widely criticised for these Clousseau-like measures, TSA eventually decided to add "enhanced screening" for travellers passing through or originating from 14 "countries of interest" as though one's choice of departure airport indicates a propensity for suicide bombing.
The TSA engages in "security theatre" bumbling pretend-steps that treat all passengers equally rather than risk offending anyone by focusing, say, on religion. The alternative approach is Israelification, defined by Toronto's Star newspaper as "a system that protects life and limb without annoying you to death".
Which do we want, theatrics or safety?
