Lost at sea: A whale’s tale

Locating a person adrift at sea is no easy task. With only a head visible, it can be difficult to spot someone bobbing on the water’s surface in the vast Pacific Ocean. Even magnified by binoculars, a shadow the size of a pencil eraser is nearly impossible to find amidst the waves and solar glare. In the case of three divers who went missing off Molokai, Jan. 18, 2016, their sighting by a boat crew could be credited to a sharp lookout and a little luck. Well, a combination of a sharp lookout, luck and a whale.
