1) tons of experience in deep sea work
2) a pretty good idea of the situation (which the rest of us mostly lack)
3) a very large budget and an inventory of resources at their disposal
4) are far from stupid.

There's a scene where they are trawling for suggestions from the public in a TV show contest - people suggest ideas, and an a panel of experts rip the ideas apart.

I wont spoil the rest of the book for you, but has anyone tried doing this with the oil leak? Engaging the public in that kind of way, not just asking for blog comments on a news article, but a real challenge in an X-Factor style big-hype approach?

It may come to that yet though.
It won't be for much longer. If I was living at the south east coast within 200 miles of the spill I'd be selling my property at a very good price right now.
