Trevor Jacob crashed a plane as a publicity stunt with the message that "a lot of pilots can learn from my experience. Please fly with a parachute." If there's one thing we learned from his video, rather than wear a parachute, it should be bring a PLB. Yes, I know the whole thing is a staged stunt, but that has no bearing on real pilots. However, do think about what you would do if you piloted your plane down to the river bed in the canyon during a real emergency. If your cell phone doesn't work, you would rely on your ELT. However, if you have to venture away from your airplane or your airplane sinks after ditching in water, a PLB could be the difference between rescue or not.
A PLB is a Personal Locator Beacon that when activated, finds your GPS location and transmits it to satellites on 406mhz like an ELT. It works around the world and does no require cell phone coverage. So feel free to ignore Trevor Jacob's silly recommendation to wear a sport skydiving parachute for every occupant whenever you fly an airplane. But, do consider purchasing a PLB to make search and rescue more likely to be a success.
If there's a second thing we learned is that his wallet is made for idiots and if you don't want to be investigated by the FAA and FBI, then don't get that wallet.
