Sounds too similar to a previous bombing plot.

New information on two passengers from Malaysia Air Flight MH370 — which disappeared without a trace off the coast of Vietnam on Friday — raises the possbiilty the plane was bombed as a terrorist test run. If confirmed, the guilty organization’s silence means more attacks may be forthcoming.

While reports remain unsettled, most agree that two unknown individuals purchased tickets for the flight stolen fake Italian and Austrian passports. More ominously, the tickets were purchased together through an Iranian middleman, known to a travel agent only as “Mr. Ali.”

Terrorist organizations usually claim responsibility for their attacks, especially successful ones. But it wouldn’t be the first time an airliner was bombed without a confession and with false passports, and some experts can’t help but compare this mystery to an earlier bombing plot.
