Airplane wings are pretty strong!

Pretty strong along that axis, but not so much on the vertical. Pitch down and gain some speed then pull back on the stick as much as possible. Result is you just snapped your wings right off at the fuselage.

They have to be strong... multiply 170 overwieght people by the gravitational force imposed on the airplane in turbulence.

That's kinda a "whoops"... wonder if they penalized the pilots, the dude who parked the truck, or both.

Panic gripped on lookers and passengers at the Lusaka International airport when a South African airways passenger plane hit into a stationary truck upon arrival from Johannesburg.
That sounded like very calm, organized, unconcerned panic.

Yep the wing is pretty much the strongest part of the plane. I once read in a book that it's built from a single crystal making it immensely strong.

Or like this... http://www.youtube.com/watch?v=pe9PVaFGl3o

Intersting to look into the NTSB report on that one to see if there was prior damage like a broken wing spar. But the plane was pitching up and carrying heavy loads + sudden turbulence flying in the mountains over heated terrain... bam.

Warning -- the video I posted is incredibly boring... until the 2:30 minute mark.

I thought that video was pretty interesting...then again I'm a (unemployed) mechanical engineer.

A single crystal composed of dozens of aluminium panels and thousands of rivets...

And it's kept cold with solution, most likely.

The spar didn't fail on that C-130 (like the Boeing test). Basically, it was a _very_ old airplane with a ton of flight hours on it and the bolts attaching the outer wing box to the center wing box were full of stress fractures. The bolts failed, which resulting in the outer wing panels departing the structure. Everything after that was symphathic failure.

Prime reason why many air forces around the world are trading in their C-130A/B/E's and buying new "J"s...

Boeing makes the 57 and 67 lower wing skin/spar at a plant a few miles from my house. I worked on the construction of the facility back in 1991.
The lower wing skin and spars are milled from one single block of aluminum.
This saves time in assembly, but the big savings is in maintenance and sealing of the tanks.
Lap joints on the bottom of the wings are a common location for corrosion, and require careful sealing to hold fuel.

I was mainly focusing on the damage area itself near the tip. Surprised it was not peeled back like a tin can. Ladies cannot wear high heels because it will damage the floors on planes, for example.

Also did the guy jump or was the shock strong enough to cause him to move the camera like that?

I think you're mixing things up... some turbine blades are made of a single crystal (grain), but definitely not any other structural components in an aircraft.
