The ATSB has stated that the latest piece of MH370 wreckage found confirms high-speed impact with the ocean, thereby eliminating any conjecture about a controlled or low-speed water landing on the part of the pilot of MH370.
If so, must be late breaking news. Here's the update on the debris finds from three days ago, looks like the ATSB hadn't seen the objects at the time:
Joint Agency Coordination Centre MH370 Operational Search Update
9 March 2016
This operational report has been developed to provide regular updates on the progress of the search effort for MH370. Our work will continue to be thorough and methodical, so sometimes weekly progress may seem slow. Please be assured that work is continuing and is aimed at finding MH370 as quickly as possible.
Key developments this week
•Debris, suspected to be from an aircraft, was found in Mozambique. The Governments of Australia, Malaysia, and Mozambique are making arrangements for the debris to be transported to the Australian Transport Safety Bureau laboratories in Canberra. The debris will be examined by investigators from Australia and Malaysia, as well as specialists from Boeing, to confirm if it comes from an aircraft and if so, attempt to establish its origin.
•In addition, suspected aircraft debris was found on La Réunion. Negotiations are occurring with relevant authorities to arrange for examination of the debris.
