Lockerbie bombing - amount of debris (confusing numbers) As mentioned on Pan Am Flight 103:


  ... In total 4 million pieces of wreckage were collected and registered on
  computer files. More than 10,000 pieces of debris were retrieved,
  tagged and entered into a computer tracking system.


This is a bit confusing, at least to me. So which one is the actual number? Or if both sentences are correct, what is the difference between them?
Pieces of wreckage implies a large 'section' of plane, whereas debris suggests miscellaneous smaller items and bits of metal etc.

I agree it's potentially confusing, however, and likely arises from two people editing the same section without adjusting the context.

I'd say that 4 substantial sections of plane were found, along with a large amount of smaller debris scattered around, totalling around 10,000 pieces.
