Nations reach deal on tracking planes

Satellite agreement may prevent repeat of the disappearance of Flight MH370

World nations struck a landmark deal on Wednesday on using satellites to track flights, which could prove key to preventing a repeat of the mysterious disappearance of Malaysia Airlines Flight MH370 in March last year.

Countries reached an accord at a conference hosted by the UN's International Telecommunication Union that aimed to improve on the current civilian flight-tracking system that relies on ground-based radars.
