A Boeing 737 that plummeted 30,000ft to the ground and burst into flames in China killing all 132 on board suffered a catastrophic 'loss of control event' and plunged to the ground at 350mph in a two-minute death spiral, experts have warned.

The China Eastern Airlines flight nosedived before smashing into the hillside and erupting in a huge fireball near the city of Wuzhou in Teng county in the southern province of Guangxi.

A rescue official reportedly said the plane had completely disintegrated while a fire sparked by the crash ripped through bamboo and trees before being put out. China Eastern expressed 'deep condolences' after confirming the fatalities.
