A friend of mine recently bicycled across America (Florida to Washington state). He had a helmet cam that he used occasionally when he wanted to share a bit of his trip. It was very cool.
Now imagine flying straight at the sea full speed for 40seconds. You hit the water, swim straight down to the bottom (150feet) and start walking (swimming?) around looking for food for greater than a minute. AND you need to get back to the surface.
Click on through, it’s really cool.
