Putting it out there, theres a whole youtube channel called "Lifeguard Rescue that is just 1-2 minute clips of wide angle shots of a waterpark pool, someone falling off their intertube and beginning to drown and the lifeguard on duty saving them.

Shows you what drowning looks like, how fast it can happen and how difficult it is to identify if you're not trained or not at an elevated angle (most swimmers within 3 feet of them don't notice).
