The only embarrassment here is that a 250 tonne aircraft can disappear off the face of the Earth, despite vast amounts of incredibly-potent surveillance and tracking technology, in the form of radar, satellites, submarines, and ships - by a sizeable number of nations.
We can put men on the moon multiple times, send rovers to Mars - yet we can't find an aircraft that disappears from the control of the most tightly-controlled transport system ever devised. There are a lot of people who must wonder where things are going seriously wrong.
Nations spend hundreds of billions on equipment for defence, and border control, and against aerial intrusions - yet employ so few skilled people in its actual use outside "normal working hours".
Asian nations invest billions in high-tech equipment, yet appear to have very few people capable of utilising it, to its fullest capacity.
Australia spends billions on JORN that is supposed to be able to pick up a Cessna 172 taxiing on the ground in East Timor, yet its áppears to be turned off, more often than it's turned on. It beggars belief.
