As the mercury appears to have been transported on the flight and was discovered on arrival, wonder if the crew got any adverse compass indications during the flight.
I know mercury is a no-no aboard aircraft, but apart from the magnetism issue can one of our chemists here explain what is the problem if it is spilled on the structure. Is it corrosive ? Didn't a Far East operator have a widebody written off some years ago due to such a spillage ?
