When the Americans were withdrawing from the Afghanistan, one of their command and control systems (used for controlling the pilotless drones) was hijacked by the Taliban, while the American transport convoy was moving down from one of the hill-top bases. The Taliban ambushed the convoy and killed two American Seal personnel, seized the equipment/weapons, including the command and control system which weighed about 20 tons and packed into six crates. This supposedly happened in Feb 2014.
What the Taliban wanted was money, by selling the system to the highest bidder. The Chinese were very eager for the technology. Just imagine if the Chinese could master the technology behind the US's command and control system, rendering the American drones useless! The Chinese sent a team of top defense scientists to check the system and then agreed to buy it from the Taliban.
Sometime in early March 2014, the Chinese scientists and the six crates of equipment made their way to Malaysia, thinking that it was the best covert way to avoid detection. The cargo was then kept in the Chinese embassy under diplomatic protection.
Meanwhile the Americans got the assistance of Israeli intelligence, and together they were determined to intercept and recapture the cargo.
The Chinese calculated that it would be safe to transport it via civilian aircraft so as to avoid suspicion. After all the direct flight from KL to Beijing takes only 4 1/2 hours, and the American would not hijack or harm the civilians on board. So MH370 was the perfect carrier.
There were five American and Israeli agents on board who were familiar with Boeing operation (the two "Iranians" with stolen passports could have been among them.
When Flight MH370 was about to leave the Malaysian air space and reported to Vietnamese air control, an American AWAC jammed their signal, disabled the pilot control system and switched over to remote control mode. That was when the plane suddenly lost altitude momentarily.
How could the AWAC can do it ? Remember 911 incident? After the 911 incident, all Boeing aircraft (and possibly all Airbus) are installed with a remote control system to counter terrorist hijacking. Since then all Boeings can be remote controlled by ground control tower. A similar remote control system is used to control the pilotless spy aircraft and drones.
The five American/Israeli agents soon took over the plane, switched off the transponder and other communication systems, changed course and flew westwards. They did not fly east to Philippines or Guam because the whole South China Sea air space is covered by Chinese surveillance radar and satellites.
The Malaysian, Thai and Indian military radars actually detected the unidentified aircraft but did not react.
The plane flew over North Sumatra, Andamans, Indian ocean and then landed in the Maldives (some villagers saw the aircraft landing). It refuelled and continued to Garcia Deigo, the American air base in the middle of Indian Ocean. The cargo and the black box were removed. The passengers had been eliminated through oxygen starvation. The MH370 with the dead passengers were then flown (via remote control) and crashed into South Indian Ocean, making it look like the plane eventually ran out of fuel and crashed, and putting the suspicion on the captain and copilot.
The Americans put up a good show, first diverting attention and search efforts in the South China Sea while the plane was on its way to the Indian Ocean. Then they came out with conflicting statements and evidence to confuse the world. The Australians were their accomplices.
The amount of effort put up by China, in terms of the number of search aircraft, ships and satellites, searching first the South China Sea, then the Malacca Straits and the Indian Ocean is unprecedented. This indicates that China was very concerned, not because of the Chinese civilian passengers, but because of the high value cargo and its eight top defense scientists.
Incredible? Perhaps we will find out in a future episode of Wikileaks
