E g yptAir Flight 804: Terror weighed as cause in plane's disappearance

(CNN) -- Planes and ships scoured the heavily traveled waters of the Mediterranean Sea on Thursday, searching for EgyptAir Flight 804 after it disappeared from radar and, according to authorities, presumably crashed into water as it flew from Paris to Cairo.

No trace has been found of the Airbus A320, which had 66 people on board, and there's too little information to tie what's likely to be a devastating tragedy to any particular cause.

But speculation immediately centered on the possibility of a terrorist attack.

"Planes today just don't fall out of the sky," CNN aviation analyst Miles O'Brien said.

Egyptian Civil Aviation Minister Sharif Fathi said technical failures and terror are both possible explanations.

"But if you analyze this situation properly, the possibility of having a different action aboard, of having a terror attack, is higher than having a technical problem," Fathi said.

For now, however, finding the airplane and any possible survivors is the priority, authorities said.
