Not sure how exactly, but apparently the technology exists:
“To answer the question of why this happened and what could have been done to prevent it, investigators will be gathering every piece of the debris they can find, according to Ryan Ramsey, former submarine captain in Britain’s Royal Navy.”

What could have been done to prevent this was for the full of himself jerk to hire some fifty year old engineers who had knowledge….oh that and do some of that useless safety testing
One doesn’t need debris to figure this out
