Stand aside. I have to host a TV show with Justin Bieber. WTF!

Sorry to correct you, but that's not a "six-sail kite" but a train of six kites flying in tandem.
To be more precise, those are revolution kites, high performance quad-line precission kites (Yikes!).
BTW, the big ghostly static kites at the back are pyro deltas.

That tape is used to detect if the crack is getting bigger

Meh. As the first he did was welding I was specting -at least- a concrete cast. Quite dissapointing.

Apparently it's called "Buggy rollin" or "Rollerman". A search on youtube returns quite a lot of results.

It is also a joke based on a security company called "securitas". Please notice the logo:

I can't understand it. Here in Spain, when we have a tunnel of a bridge that low, we place a soft metal arc some meters away.

If your truck is too high, you will hit the arc, but that won't be so terrible.

A good "Pata Negra" leg costs in Spain something around $100, a reeeally good one can get to $500 or so.

Prices in London are simply ridiculous.
