Why didn't anybody manually activate the ELT?
I didn't see a reply to this, but here's my simple take on this: The last thing you want when fighting for your life and asking for help, is to jam your radio. That is why military pilots are trained to turn off the parachute beacon ASAP. If you are transmitting on 121.5 (or 243.0), then you can't talk on it. If you can't turn it off (you're hurt or unconscious), then you want it to automatically turn on.
