The report was puzzling by lack of detail.
I just finished a Google search on all the available reports. Some are using the word wreckage but no additional information. Its odd for sure.
The pilot and co- pilot have a small radio attached to their shoulder that will give a one way transponder signal and a short distance two way comm so if either one of them is alive somebody should know by now. If rescuers are near they should be able to talk to them.
