New pings detected, but no wreckage spotted

Searchers are reporting another possible new ping in the search for Flight 370, but so far there is no sign of any debris from the missing plane. Gary Tuchman looks at the kind of wreckage that can be found, and what it might say about how Flight 370 may have gone down.

Anderson discussed some of these scenarios with former Department of Transportation Inspector General Mary Schiavo, CNN safety analyst David Soucie and David Gallo, who co-led the search for Air France Flight 447.
