That is in fact a Europa, the trigear version, luckily for the occupants. The other version has a monowheel undercarriage. It's a hombuilt and composite. I remember seeing a picture of a Cessna 150 in the US hanging from powerlines in similar way. Most of the time, hitting powelines doesn't end so happily. You can literally lose your head!
That is also my recurring nightmare, hitting high tension lines. They were very, very lucky. There are powerlines to the east of the runway at the skydive field I operate out of. On approach I like to pass over them at about 500 feet. But they are surprisingly hard to see. But on taking off from the easterly runway on a hot calm day with a full load. They often seem far too close. 
The term 'bending the throttle lever' comes to mind (and the prop lever!)
I just shudder at the thought of them.
the high tension lines are hard to see. the towers are very easily seen.
i use em as a landmark at the fling w if i'm landing on 19. as i approach them, i start m base turn...this takes me ever so slightly past them.....i palallel them, then turn final.
a few years ago when we were on a SAR mission for a crashed helicopter, we were concentrating around some of them about 20 miles south of the "W". we had seen pcs of the heli(homebuilt), and it was equipped with wirecutters. this lead us to believe they were running very low, and "playing".
they weren't near the wires, but were staying low.....which cost them, as they ran out of fuel, and went in. they fell short of a highway by about 1,000 feet.
