Technology exists to record all parameters of flight in real time with every jetliner on the globe in controlled and uncontrolled airspace.

You vastly overestimate the state of the world. I explain this to my kids all the time. Most of the world doesn't live like us. Most of the world is poverty stricken and poor. There are a few big industrialized nations but even of those only a handful live near the same standard that we do. What we have is very very rare yet even our air traffic control system is 30-40 years old in some cases. There's no way that these companies keep as good track of airplanes as you think they do. Without the USA, there wouldn't even be a GPS.
