Breaching humpback whale nearly crushes kayakers — VIDEO

A massive humpback whale nearly flattened a pair of kayakers on California's Central Coast when it launched out of the sea and landed on their boat. 

Nearby whale watchers looked on in fright as the creature flipped the couple into the water Saturday near Monterey Bay's Moss Landing Harbor. A video filmed by a Sanctuary Cruises passenger and shared by the company on Facebook shows the whale's "full 180 degree breach."

One passenger can be heard asking anxiously, "The kayak! The kayak! Where's the kayak?" followed by applause when the couple appeared unharmed.

A full-size humpback whale can weigh more than 40 tons. Sanctuary Cruises captain and co-owner Michael Sack, writing about the encounter on the company's blog, said it was "one of the more dangerous situations that I've seen out here."
