What's truly astonishing is the gap between the 92% achieved by the US and the comparatively pitiful 72% European success rate. If you were to take the US out of the equation, the overall average decreases to 58.4%. The US rate of achievement is thus perhaps reflective of the capable, accountable and efficient authority to be found in the FAA.
True. However, it also depends how 'Europe' is defined. If this includes Russia, well, I guess that explains it.
The 41% for Africa are still scary, though....
