Anyone aware if it's merely urban myth that, in an emergency even over land, pax are instructed to put on lifejackets so that bodies are more easily discovered in the event of a catastrophic crash, and that the brace position is designed mostly to preserve dental records?
Yes, it's a myth, just like the story that the drug sniffer dogs are addicted to drugs and are looking for a fix, or that one that when you flush the airplane toilet the contents are dumped through a hole in the bottom of the airplane, falling as giant icicles on homes below. All this belongs in jet blast. But the one about writing "fast, neat, average" on a napkin is partly true, or was.
