asi to s těma tvejma znalostma nebude tak žhavý:
Radar coverage of the area where flight MH370 went missing is patchy and often not even switched on, according to aviation experts.
It has emerged today that civilian systems do not cover large swatches of the areas the plane could have gone, and that military systems are often left off to save money.
Air Vice Marshal Michael Harwood, a former RAF pilot, said: ‘Too many movies and Predator [drone] feeds from Afghanistan have suckered people into thinking we know everything and see everything.
‘You get what you pay for. And the world, by and large, does not pay.'
Air traffic control teams rely transponders signals to track planes- but investigators believe that the device was intentionally switched off on the missing aircraft.
Military systems, meanwhile, are often limited, switched off , or routinely ignore aircraft they do not think are suspicious.
A Rear Admiral in the Indian armed forces, which are aiding search efforts over the Andaman Islands, said: ‘It's possible that the military radars were switched off as we operate on an "as required" basis.’
However, experts have suggested that a disappearing transponder signal would be treated more seriously over Europe or America, and that a parallel situation would be unlikely to develop.
mě je docela divný, že zatím co profíci z oboru se neodvažují spekulovat a opatrně tvrdí "že stát se může ledacos", tak Janko v tom má jasno.
