better things to spend money on than this needle hunt??
Well, apart from world peace and curing cancer etc, I don't think so. Yes, it is sort of amazing that the airline industry and governments are prepared to spend money on chucking bits of plane into the sea to find out where they come ashore, but the incredible safety of commercial air traffic has been achieved by obssessive seach for the explanation behind crashes and by obsessive logging of data about equipment and flights. (Who for instance outside the industry would have guessed that satellite handshakes were logged in enough detail to work out the speed of the plane two years later, based on doppler shift!)
So I am pleased the hunt for the plane continues, because while the crash is unexplained there is nothing we can do to stop it happening again, and I might be on the one that crashes the next time.
