This guy's conspiracy theory on MH370 goes all over the place and is so out there involving secret superconducting technology and Chinese espionage trying to steal it from a US military lab that employed Chinese scientists to create this technology in Malaysia and not the US that somehow ended up with the US using this secret technology in vehicles that intercepted MH370 and made it disappear...
It's like the US bombing the Chinese embassy in Yugoslavia. There are Americans that would rather believe the US intentionally bombed that embassy than believe they made a mistake. Just as long as it portrays the US as in control, they'll believe it. If MH370 incident was due to a simple malfunction, guess who's going to be sued? The US because it was a Boeing aircraft and the British who made the engines.
I have my own conspiracy theory because why would an accident need to be covered up? Why the elaborate ruse? I have no proof this happened but by Occam's Razor is the simplest conspiracy theory based on real geopolitics. That area where the plane disappeared was already under intense scrutiny over territory disputes between countries in that area and not just with China. In that type of situation, planes can accidentally be shot down by militaries for illegal encroachment. MH370 was heading towards to fly over Vietnam when it disappeared. I recall it being said that communications with the aircraft was about to be switched over from Malaysian air flight control to Vietnam before the fight disappeared. What if it was Vietnam that shot down the plane not knowing it was a routine commercial flight? Since it was full of Chinese passengers and because of testy territorial claims between China and Vietnam, Vietnam called the US for help because they thought China could use this as an excuse for military action against Vietnam. So the aircraft crashes in a remote area of Vietnam where all the parts of the aircraft and bodies could be retrieved and destroyed while the US and Great Britain sent everyone on a wild goose chase because of a suicidal pilot theory. And who is in control of all this GPS information saying where the plane could've went and crashed...? The US and Great Britain who would be responsible if the aircraft went down due to a malfunction which they couldn't claim for their own interests. And to make it more believable save some pieces of the aircraft and drop them somewhere in the India Ocean off of Africa to help confirm the theory that it intentionally veered off towards the Indian Ocean.
