Re: "having a load of Lithium batteries in the hold sounds like a bad idea to me."
Reminds me of the ancient joke about the fellow who consults a psychiatrist because of his morbid fear of being on a plane with a bomb on board. After the usual chitchat, the psychiatrist points out the huge odds against such a thing happening. When the patient still demurs, the psychiatrist suggests, "Why don't you take a bomb on board yourself? The odds against being on a plane with TWO bombs are far greater still".
