Irate families of passengers on board a missing Malaysia Airlines flight pelted airline officials with water bottles and demanded answers to what has become one of the most perplexing aviation mysteries in recent years.

The video, which was taken Monday in Beijing, shows several water bottles being lobbed at airline officials, who stood at the front of the room to deliver the frustrating news that no new information was known about the fate of the doomed Boeing 777.

The families were eventually bused to the hotel about 15 miles away where the awful reality became apparent.
