very interesting .... I mean someone had to think of that!
Wouldn't you have loved to have been in the room the first time someone suggested that?
This is interesting how this guy Grounds the helicopter to the high voltage lines so can work on them.
Technically, he's not grounding the helecopter. He's energizing the helecopter so there is no potential difference between it and the power line he is working on.
...the helicopter platform is isolated from the helicopter itself, the platform is what is becoming energized, or brought up to equal potential as the line voltage

Flog Zog, thats funny.
It is a cool video though, I used to show it to my students back in my teaching days.
They had video back then?

The helicopter itself also becomes line potential.
Actually,the live high voltage lines have residual charges on them so that when the ungrounded electrician touches them with his bare hands,he may receive a shock.To prevent this he touches the lines with his wand to distribute the charges equally.helicopter blades give off static charge, which give the arcing when connecting to and from helicopter
My brother in law used to light his cigarettes with the arc he could draw from his safety lanyard and a transmission line.They call it 'bonding on'.
'Bonding on' is a part of 'bare handing'.
This is how it's taught:
