The first one is not really a incongruity, I think. consider this: If a plane crashes, you can find the passengers clothes and even their suit-cases. Often, they don't look particularly harmed - and still, there are no or near to no survivors. Obviously, baggage (as in fabric and other non-fragile objects) can take quite a beating without being vaproized, as you put it. Human, on the other hand, are very fragile living beings. Especially when the inner organs get too much of a shove (like from the crash), they suffer fatal internal injuries. In many cases, the body looks outwardly unharmed to boot - or so I read somewhere.
About the second one: I think you're right there, it is a contradiction. But since a man defying gravity on a regular basis isn't any more logical than this, I decided to go with it.
