MH370 Passengers. They're Still Alive?!!

In Beijing on Saturday, some of the relatives of the missing vented their anguish in the streets.

"They're all still alive, my son and everyone on board!" yelled Wen Wancheng, 63, whose only son was among the passengers. "The plane is still there too! They're hiding it."

He held aloft a banner that read: "Son, mom and dad's hearts are torn to pieces. Come home soon!"

Many relatives doubtless remember the speculation from early in the search that the plane may have landed somewhere. They implored Hishammuddin to redouble the efforts, and he said Malaysian authorities would do so.

"What they want is a commitment on our part to continue the search, and that I have given," Hishammuddin said. "For me, as the minister responsible, this is the hardest part of my life, at the moment," he told reporters.

"Miracles do happen, remote or otherwise, and that is the hope that the families want me to convey -- not only to the Malaysian government, MAS (Malaysia Airlines), but also to the world at large," he said.
