PARIS (Reuters) - Fresh questions have been raised over air traffic co-ordination after a preliminary report on the Malaysia Airlines plane that disappeared almost two months ago revealed 90 minutes of wasted effort while controllers looked in the wrong country.
While Flight MH370's disappearance has led to calls for real-time tracking, it has also re-focused attention on the gap between what controllers sometimes think and see, which complicated early efforts to find Air France 447 in 2009.
