This is a good example of quick thinking in a whitewater kayaking rescue situation (that I somehow found in surfing around for a video for work - no, really, seriously. :) The video shows a kayaker rescuing a pinned paddler on the Cheoah River in North Carolina, taken from the rescuer's head-cam.
It's super easy to be a back seat driver in these situations, but in reality it is extremely hard to react so quickly and make a lot of good decisions, as happened here. I think he did an awesome job of quick thinking and planning the extraction. Thumbs up to the pinned boater as well for keeping her cool, which is not easy to do.
