It's six metre waves. That's 20 foot waves. If I were on the deck of an installation and there were 20 foot waves, I would be reluctant to get on a helicopter, especially if I thought something might go wrong, or there was fog, or whatever. That's the danger, I think. Scheduled flights are going unless they shouldn't go, whereas the more appealing concept to me is, “We'll look at the situation and if it's right, let's go.”
