Philippines ? Divers managed to get inside an upside-down ferry today but found only bodies and no survivors three days after the vessel capsized during a powerful typhoon with more than 800 people aboard, officials said.

Philippines Navy spokesman Lt. Col. Edgard Arevalo would not speculate on whether anyone still might be found alive but indicated the amount of time passed since the disaster made it unlikely. He said the ship’s interior was too dark to even determine how many bodies were there.

“Most of the bodies were floating inside. They were trapped when the seven-story ship suddenly tilted and capsized,” he told dzBB radio.

Arevalo said it was possible some passengers could have survived initially, but the roiling seas had kept rescuers at bay too long and suffocation may have claimed some lives.

He said some of the bodies had life vests but many passengers apparently hesitated to jump into the “turbulent waters” before the ship capsized because “it happened too sudden.” Survivors said the ship listed and went down in a half-hour or less.
