Certifying death
If a passenger dies on board a British registered aircraft, say over the ocean a long way from anywhere while it is on its way to London, can a doctor who happens to be one of the passengers certify the death, or must this wait until arrival in London? Suppose it was a heart attack and the individual, even to the untrained eye, is obviously dead, is it acceptable for the captain to rely on a written note from a doctor whose credentials he was able to verify? What does the UK law have to say?
