there is NO other airfield big enough for B-777 to land except Diego Garcia!

If the airplane hadn't already crashed, instead, had indeed reached and is hiding in Diego Garcia, then it's EXTREMELY, GRAVELY dangerous for whole China like never before in history!  I cannot elaborate here at this time.  I didn't want to refer to it in the past week because that implication, if true, is way, way too ominous and horrible by any human imagination.  That would require an unbelievably sinister, demonic mind to think of and plan that kind of malicious ploy.  I'll wait a little bit more time to see what really develops next before any meaningful reference to it.

For China, the only thing I can say right now is, if MH370 cannot be found, then from now on, turn on ALL radars, 24/7, everywhere in China, monitor EACH AND EVERY FLIGHT in the sky above China, whether it's scheduled or unscheduled, known or unknown!  If any suspicious plane is discovered, stop it ASAP.  Force it to land immediately,  If it does not comply, or cannot make it land, then no other way, shoot it down right away!!!  The severity of the consequences is way above the scale of anything that has happened in the past history (even 1850-1841 1366-1365 1503-1502 is not remotely comparable)!!!

I hope MH370 can be found timely in any manner, by any way!
