My view of what happened with Malaysian Flight 370 is that it was brought down by laser-rocket fire in the South China Sea by US forces gathered there, and still there, and was due to human error. This is the most contested, viewed and studied area of just about the whole world and the US Navy and Air Force is there in Bulk to continually ping and test and find faults in China's Air and Sea defences, all the time. That's just what they do there, all the time. It is understandable that human error caused the incident...but it was a human error that the US could not take responsibility for. I believe the Chinese know this...thus the ongoing military build up of the islands off China to secure both sea and air travel for the future. If the US could do that by accident, what could they do on purpose? Mind you, for the grieving families, this reality probably isn't acceptable...thus the manufacture of something impossible is better for them? After all, most of the passengers were 'Only Chinese'.
