Malaysia Airlines Flight 370: "None of those on board survived"

The surviving family members of missing Malaysia Airlines Flight 370, heard the news they feared most: "all lives are lost".

For many, it was too much to bear.

A woman who left the Monday's press conference screaming, expressed doubts about the Malaysian conclusion.

"Where is the proof?" she said. "You haven't confirmed the suspected objects to tell us no one survived."

Seventeen days after the passenger jet disappeared with 239 people on board, emotions were high, ranging from blame to disbelief. While Malaysia's prime minister dashed any hopes of finding survivors, there are still many unanswered questions.

'They have told us all lives are lost,' says relative of Malaysia Airlines passenger

Heidi Snow lost her fiance on TWA Flight 800 and is the founder of ACESS, Aircraft Casualty Emotional Support Services. She's been speaking with some of the families of the missing and is Outfront.

"It reminds me of what it was like after Flight 800," Snow said. "There were a lot of new leads. Some of them were very tangible and other times they really didn't add to what we needed to hear. This isn't enough evidence to change the grieving process."
