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.

"Malaysia Airlines and others are not doing their jobs, so we have to organize," Wang, who abandoned graduate studies in Sweden to be with his grieving mother, said via Skype from his home in the city of Anyang.

"I cannot live the rest of my life with questions."

Through a Chinese micro-blogging site - 153 Chinese were aboard MH370 - a closed Facebook group and Skype "meetings" of up to dozens of people, participants exchange findings, discuss the latest theories and make proposals for group action.

The group, calling itself Voice370, with some 300 members, receives and debates advice from aviation, legal and other experts, while similar groups formed after previous disasters such as the 2009 Air France crash offer support.

While some face-to-face meetings have been held, most exchanges are conducted via webcam or extensive e-mail exchanges, with members voting on strategies for pushing Malaysia Airlines and governments involved in the still-fruitless search for more information.

In doing so, they juggle time zones and language barriers - meetings are held mainly in English, with bilingual Chinese translating for their countrymen.

"It's really quite a community," said Sarah Bajc, a US citizen whose partner, Philip Wood, was on the flight.

"I feel compelled to do everything in my power to find Philip. We owe it to them."

Flight MH370 disappeared with 239 people en route from Kuala Lumpur to Beijing.

No trace has been found despite an extensive, Australian-led search in the southern Indian Ocean.

Some relatives have sharply accused the airline and Malaysian authorities of a bungled response - its military tracked MH370 on radar after it mysteriously diverted, but did nothing - and withholding data from the public.

Yet despite their efforts, families have seen only modest success.

In an open letter to authorities in Malaysia, Australia and China in May, a skeptical Voice370 demanded to see satellite and other data that Malaysia says indicates MH370 went down in the Indian Ocean.

The information was eventually released but shed little light on what happened.

In June, several family members, including Bajc, launched a drive to raise $5 million for any whistleblower with information on the jet's fate. Only $100,500 has been raised.
