Disclaimer: If you had an incredibly close encounter with a killer whale you'd probably use a couple of curse words. Even if you wouldn't, the people in this video did, so consider yourself warned.
There isn't a whole lot of information on this video but what you will see is that this group of kayakers is either very brave or very stupid. We start with a far out shot of a group of killer whales swimming and leaping in and out of the water. As the group of giant whales comes closer, the group simply stays put and keeps filming. All of the sudden, the whales are popping directly in front of the kayakers before they re-submerge directly under the stunned videographer. 9 times out of 10 this story probably has a very different ending.
