In photos: Missing EgyptAir flight MS804

An EgyptAir plane carrying 66 people disappears off the radar Thursday morning over the Mediterranean Sea en route from Paris to Cairo.

While a massive search in under way, Egypt’s aviation minister says the A320’s disappearance is more likely to have been caused by a terrorist attack than a technical failure.

A day after the plane vanished, the wreckage has yet to be located.
