I believe Widmore and Paik combined have resources to fill the oceans with fake wreckages... and bodies as well. We saw last week Widmore personaly kick the crap out of one of Ben's spies right, who knows how many more people each man of power has killed himself.. I mean Paik sent Jin to 'talk' to a few people that we've seen in his limited flashbacks.

The problem I had with the epi is, and it should show that Widmore and Paik DID fake the wreckage, is why would the captain have the black box. Shouldn't the FAA or whatever Austrailian authority have that device? I think it shows that Widmore had to grab it, OR never put it in the downed plane so no one could find out where the wreckage really came form.
