You mean you don't know?

Always worth reading the comments

What of course it's real, law of physics means you will of course stop dead at that speed when landing in 2 feet of water.

The splash looks right ,but some fakers are good .

Some are yes but that Whale one is terrible, everything is grainy except the whale.

Mythbusters tried to do it and at the end of the program said that they'd been in touch with the people who made the video who confirmed that it was faked!

I assume you are joking!. mythbusters did a show on this and it was suprising how accurate they could be in terms of landing but certainly could not get the distance.
