For family of the passengers on Flight 370, the wait is excruciating.
"If I had 2 or 3 children, I might be able to accept it, but this is my only son," said Gurusamy Subramaniam, whose son is on Flight 370.
Subramaniam is waiting for his son - a 34-year old Puspanathan, an IT specialist who was headed to Beijing for a new job.
"Surely, they must find the plane. That is all i hope for. The whole world is looking for it," said Subramaniam.
What if they don't?
"If not, god only knows. It is god's hands. It's fate," he said.
He tells me he worked 20 years as a security guard to put his son through college. His younger sister followed in his footsteps, and at home, a wife and two young children also wait for him.
"He was responsible for everything. These clothes I'm wearing even. Whatever country he was in, he would call. Once a week, he would come see us with the whole family. He really took care of us."
He said the two young children didn't want their father to go to go to Beijing. So, they clung to his legs and refused to let him go out the door. Until he promised to bring them chocolates and presents when he got home.
Before CNN left, he tells them to call anytime with any news we have: He hardly sleeps, he says, and now he never turns his phone off, not even for a moment.
