No. Not really. Where it is may be where it's supposed to be. Not knowing that doesn't make it lost. Ex: If I send a ship to sea before we had radio/telegraph, I may not know where it is at any given point, but it's not lost and I don't need to go find it. It's lost when it misses a check-in, and what constitutes a check-in is really company/org dependent.
