I would like to point out to some of the newer posters...
why can't we track planes? well, I was watching CNN the last two days and they couldn't keep telephone guests online...the phone was invented about 140 years ago or so and we still can't keep a phone line up to allow an interview. SHOULD we spend millions of dollars for better phone lines?
ITS all about money. Are you willing to pay X amount MORE for your ticket if the plane has a 1 percent great chance of being found in 3 days after a crash?
AS to survivors in life rafts waiting for rescue. During WW2, many survived for WEEKS in life rafts before rescue. IT SHOULD BE NOTED that many if not all life rafts may have flare guns, signaling mirrors and ELT transmitter. I certainly am NOT privy to the exact equipment on this airliner, perhaps others can help us on this .
I do not think there are survivors in life rafts as they would be trying to signal if they possibly could.
BUT we may get lucky and find someone. And I am praying that they do.
