MH370 families unite to seek answers

Chinese physics student Jimmy Wang had no interest in aviation until March 8, when Malaysia Airlines flight MH370 disappeared with his 58-year-old father, Wang Lijun, aboard.

Wang, 31, now spends evenings in Central China combing through aviation blogs for Boeing 777 technical specs, exchanging what he finds with other MH370 relatives.

He is one of hundreds of relatives who - desperate to learn the fate of their loved ones - are channeling their grief in a cross-border, social-media-enabled, but so-far frustrating citizen campaign to solve aviation's greatest mystery.
