This is totally ridiculous.
People in the US must have someone to blame for everything that happens to them. If an asteroid were to strike the earth, anyone US citizens, left alive, would be looking for a lawyer, so they can sue the grand exalted ruler of the universe.
There is no currently available technology that would have guaranteed that this man would not be injured in such an extreme accident. But Lawyers, in this misguided nation, have shown the general public how easy it is to get MONEY, from, easily mislead jurors, so SUE SUE SUE!
