Triangle des Bermudes: l'énigme révélée

I found this to be a lot more interesting than expected. I originally put it on because I was super bored and expected it to be a bit fantastical given the Bermuda Triangle urban legends. But the film covers some real issues that I hadn't heard of before, such as blue holes and methane hydrate, and give real explanations of them.

I also liked the discussion about whether the Puerto Rico trench could cause tsunamis, and the discussion about breakers being more dangerous in calm water than stormy water.

On the whole I think this has turned me on to the "drain the" series and I look forward to more.
