The one thing gleaned from viewing at least 25 articles on the web about this missing helo. is that not a one of them has reported that the a/c has been physically found, even though most headlines in fact state that the missing helo. has been found.
The closest to finding the helo. so far, is having a ping described as the last known location of the helo. based on where the ping is thought to have originated.
if there’s nothing but a last received ping location, then it could be a managed blackout of a crash with injuries or worse.
i’m not sure if military aircraft even have ELTs. maybe they have a military version which operates in a different mode due to the possibility of location detection by a possible enemy.
