Wing part could help solve what happened to MH370

The surprise discovery of the debris on a rocky beach stirred hopes and emotion among families of the missing, after a year and a half of grieving and frustration at a lack of answers, despite a wide, deep and expensive multinational search effort in the southern Indian Ocean, the China Sea and the Gulf of Thailand.

Even if it is confirmed to be a long-awaited first clue to the disappearance of Flight 370, there's no guarantee that investigators can still find the plane's recorders or other remains a year and a half later.
