Hats off to Airwon, there's something in my brains logic that says you just shouldn't mix water and electricity.
From the programme it was clear that Air2 take the safety of their ops very seriously but it's interesting that the UK and US seem to have different interpretations of what's allowed on live o/h lines.
I wonder if in the UK they're allowed to powerwash live 11kv insulators from the cherry pickers? I'd be surprised.
