There are hundreds of planes known to have been lost in Nevada. Many
have never been found. In the course of doing *this* search, they've found
some wrecks that were not previously known. For each of these newly
discovered sites, investigators are being sent in to gather information
and identify the aircraft. Families will be notified of the findings. Bodies
are unlikely, given the time since the crashes and the scavengers that
inhabit the deserts and mountains. It's a *very* remote part of the world.
It's a big search, for a famous person. Other people are searched for too,
but if they're not found after a few weeks of looking, the safe assumption
is that they're beyond help and no further organized effort is justified.
Searching is not without risk; if there's a chance of recovering a pilot
alive, that's one thing. It's quite another to put a lot of pilots at risk looking
around for a dead body.
This past weekend climbers on Mt. Hood here in Oregon were up looking for
the bodies of two guys who were lost on the mountain last winter. They're
pretty sure they know where they were, but the crews didn't find any sign
of the bodies. They may never be found. They're looking now because it's
late in the season and the snowpack has melted back far enough to
possibly reveal the bodies.
A paraglider pilot I knew some years back was lost in the Alps, when he
went off for a flight and disappeared. We organized a search for him, but
after a week or so of no trace, it was clear that wherever he was, he was
beyond our help. Nothing has ever been found of him or his wing, but I
expect that someday a climber or hiker will come across his remains.
