He's been so focused on helping Mark Morley that he hadn't noticed that his own suit is now taking on water too.

He can barely feel his legs, and he's more tired than he's ever felt.

He's probably been drifting in and out of consciousness without even realizing it.

He sees Morley floating a few feet away and swims over to help him.

Once he has the skipper's head propped on his chest, he slaps himself on the cheeks a few times.

He has to stay alert.

For his skipper.

For himself.

For all of them.

Another helicopter must be on its way.

Captain Ted Lefevre gathers with his helicopter crew in a side room just off the main hangar at Sitka Air Station.

Everyone is ready to go.

Under their flight suits, each man wears a polar fleece dry suit.

On their backs, they carry a pair of scuba tanks.

The tanks and the dry suits are precautions in the event of a crash, a scenario Lefevre tries to put out of his mind.

He's about to order his men into the hangar to begin their pre-flight checklist when pilot Steve Torpey speaks up.

Sir, I don't think we can leave yet.

Lefevre is stunned.

It's now 11.35 p.m.

Those survivors have been in the water for four and a half hours.
