this probably won't turn out well...

Lost aircraft generally are involved in a crash, the aircraft integrity is compromised.

The design parameters of the two objects are different, the boat is made to survive the ocean, the airplane is made to survive wind resistance.

Also why didn’t the beacons continue to locate the boat after the rescue? Were they just turned off when it was abandoned?

We had an epirb on one of our boats but at the time (late 80s / early 90s) these were pretty old technology.

Aircraft have a 100% chance of sinking after crashing into the ocean. They end up on the bottom of the ocean, and the oceans cover MOST of the planet. The pacific alone is 62.46 million square miles. Try finding anything that is made of metal on the bottom of the ocean. The oceans of the world is 140 million square miles, there uncounted thousands of boats on the bottom of the oceans and lots of airplanes.

I don't think we'd get a signal from a transponder on the bottom of the ocean.

It didn’t start out in the bottom of the ocean did it?

I’m just a dumb engineer but I imagine that if the car manufacturers are able to put a couple of accelerometers onto a PCB and write some software that fires one or more explosives off within a vehicle (airbags) based on a shock followed by deceleration criteria (acceleration and direction) of a vehicle, aeronautical engineers should be able to write similar software that switches on an emergency beacon based on a rapid descent followed by a shock (plane falling out of the sky and crashing).

Even Abby’s boat had a beacon that was set to turn on if the antenna becasme submerged by more than 15’... maybe start there. This chit isn’t impossible or insurmountable.
