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.
Prayers.
Reports describe wet and snowy conditions in mountainous terrain. If crew and passenger compartment compromised (opened) by crash and Marines so injured as to be unable to communicate since touchdown that ain’t hopeful.
Do the military ever cancel non-critical flights into terrible weather just for safety?
