And that area of the North Sea provides a LOT of the fish we eat here in Europe. If TOTAL plays down the effects of the leak to the extent that BP did of theirs, the true dimension of the damage won't be known for a week or more. Already, the fact that low-flying (under a mile) aircraft have been barred from flying anywhere near there gives an indication how much gas has already leaked out. And this is after only two days. If it takes six months to cap the leak, one spark could lead to one very big ka-boom indeed.
