I'm shocked that in 2016, we can't pinpoint to a fairly decent degree of certainty where the aircraft could be after 24hrs of daylight since it went missing.
I don't blame you from being shocked, considering the following:
The last successful reception of telemetry was received from Pioneer 10 on April 27, 2002; subsequent signals were barely strong enough to detect, and provided no usable data. The final, very weak signal from Pioneer 10 was received on January 23, 2003 when it was 12 billion kilometers (80 AU) from Earth
Twelve - billion - kilometres. How many nautical miles is that?
I would assume the technology exists but not the need to know?
Maybe it's not too shocking after all.
