The problem is the missing debris. I’ve posted prior that given the fact they’ve been searching in the wrong area for weeks due to reliance on the geeks from Inmarsat, there should (ironically) be debris washing up on beaches in Malaysia in the next week or so.
If it broke up, there is floating debris (AF447 produced a debris field several miles long after just a few days); they’ve just been looking in all the wrong places...if it went in controlled, it was daylight and a calm ocean could very well see an intact fuselage (which, if one theory is proved, would be exactly what one would want if he/they wanted to ‘prolong the pain’, i.e., the ‘mystery’...).
This plane landed in a relatively smooth open ocean.

US Airways, Capt Sullenberger's landing, was a masterpiece but on a protected inland waterway.
I agree that debris will wash ashore traceable to the missing flight. That may include bodies and body parts.
