The statement above that a 406 Mhz locator would have solved the search problem seems a bit on strung out on
Hopeium. Technology, while nice to have, does not imply that your ass is completely covered!
The KEY problems with any of these devices is, will / did the device itself survive the crash, much less the associated wiring and antenna connections.
Re-reading the crash report above and having seen some of the photos,
I doubt that any electroninc device would have survived that grinding, strung out crash.
I once worked on the first AMPEX MR-100 Missle recorder, and have seen and repaired some of the "recovered" units after they crashed. Not Pretty.
A lot of these devices reportedly fail because the transmitter becomes separated from the antenna, or the plane goes on its back and sticks the antenna into the ground.
I personally have my PLB mounted where I can trigger it with either hand while still flying the plane,
and if things look like they are not going to have a comfortable outcome. I would turn it on as soon as I become committed to a ugly result. Better to get some form of signal out while there is a chance of the signal getting out. Have even thought of designing a small parachute for the damned thing so it might survive even better, and still end up close by.
