Uhhg... what fantasy land do you live in? Please give me one example of a large widebody jet *landing* on the ocean and remaining even close to intact? And if you mention Sully and the A320 on the Hudson... immediate disqualification - a relatively smooth and calm river is NOTHING like the Indian Ocean on ANY day of the year.
Let me use your intuitive assumption in this case, if it is not possible for a big aircraft to stay intact after ditching in waves, coupled with the fact that Inmarsat is pointing in the right direction, we should have found atleast some debris by now. You have to keep in mind that search effort is also going on using satellite imagery by multiple nations and TomNod,not counting ships that arrived into aearch area from different directions.
1. Big plane loaded with passengers, luggage and cargo
2. Thousands or more floatable plastic parts
If the aircraft did not stay intact (a highly logical assumption), atleast some debris should have been spotted by now. However, lack of any debris discovery anywhere (Aircraft,Satellites, Ships) argues that in this case the plane possibly did not break apart.
