Very skilled - but then you don't get to pilot one of those whithout being a pretty good pilot, like ex-military (helicopters being so much harder to fly even than fixed wings 'planes), and when you think about the size of helipads on rigs/ships etc, I don't suppose the mini roundabout was so much smaller...
The thing that gets me, seeing those helicopter rescue shoes on telly, is when they are trying to land on a steep mountainside, and having to watch the rotors against the slope of the hill above, and sometimes then have to hold it balanced on one wheel/skid while the medics get out, because the ledge they've landed on is so small...
