Aging couple went for a landing but didn't see the power lines.

I wonder why they weren't fried?

Sorry about the language of the original (Dutch) but couldn't quickly find
an English report.

From the video it appears that they've bent the pylon such that they're
hanging clear of the other cables. So there was no current path. Also,
the wire they've hit is the one that runs across the top of the pylons.
That's a ground wire.

Which would be connected to ground.

It's to persuade a potential lightning strike that "we are a gooood keeeed"
and we are actually on the ground so don't bother us and go for something
else that's sticking up :-) Similar to the 'lightning arresters' used on
house chimneys etc. That overhead conductor is earthed at every
pole/tower. I suppose it's a bit like a Faraday cage. Ergon (all of Qld
except the SE corner) uses an aerial earth over sensitive conductors, eg
near reclosers and zone substations. The explanation may be a bit suss as
I'm a mech/civil rather than elec engineer, but it'll give you the basic
idea :-)

SWER - aka Mandeno’'s Clothesline.

Named after the Kiwi who invented it in the 1920s.

Once upon a time he received quite handsome royalties for every mile of line
constructed. Not sure if this still applies but there are some 200,000 km of
SWER reticulation in Oz/NZ.

.....and bloody impossible to see when some bastard plants the poles amongst
the trees on top of two hills about a kilometre apart.
