"The US military has joined efforts to stop an oil leak in the Gulf of Mexico as fears rise about its scale."The oil rig disaster off Louisiana is the top news item on the NY Times and BBC.com. The "transmission losses" from this one event now include not only the oil leaking and the environmental consequences, but also the costly involvement of the US military.
Same "transmission losses" when everything goes right, of course. There are always leaks, though not at this scale. There is always the US military, ensuring safe passage for tankers in another gulf. Now to protect our shores they are assisting industry to mitigate the mess, in this case BP. (Beyond Petroleum, really?).
