Why is it impossible to think they landed it somewhere?
And that’s why no one can find anything.

I find myself also thinking the same, until the recent posting which indicates fragments of plane have been located. Unless, the fragments were placed as a red herring.

Noted in a comment at a much earlier related FreeRepublic thread, the transponders on these planes were recently disabled and many of these planes are serviced in Malaysia:

"last year, Boeing directed operators of its various jets to replace Honeywell Emergency Locator Transponders on their aircraft. The models involved included the 777-200. A Honeywell transponder on a 787 owned by Ethiopian Airlines caught fire on the ground in London and heavily damaged the aircraft."

Malaysia Airlines Says Plane Had No History of Malfunction

Last Safety Inspection 10 Days Ago, Which Was Earlier Than required, It Says

Malaysia Airlines said its missing plane had its last safety inspection 10 days ago--earlier than required --and didn't have a history of malfunction. WSJ streaming updates

"...what is shocking also, imo, is the number of planes flying for domestic US airlines that have their maintenance performed in malaysia. http://mae.malaysiaairlines.co...

It is looking more and more like it came apart at 35,000 ft. Spreading out the debris field over a very large area.
