this morning we're following the latest breaking news in the search for malaysia airlines flight 370. a chinese plane has reported what they're calling suspicious objects off the coast of australia, that as cnn has learned the plane dropped down to 12,000 feet after making its turn off course. there are many theories about what may have happened to flight 370. one of them is called the shadow theory, and it's not impossible. chad myers explains. >> the shadow theory says that flight 370 flew to the northeast but only to waste time, to turn around and fly back over here in order to catch up with a plane that had left singapore later and they would fly together as one plane on the radar off toward the north and toward the northwest, somewhere up that way. we don't even care about that at this point in time. is it possible?
