Yup Im getting that, so it would be interesting to see if there is some mathematician can figure the speed, the impact potential of the WTC building, how much G's would have been absorbed by the plane itself and how much G's would then get to the blackboxes. Blackboxes should be installed near the tail of the plane, so much of the G' force Im guessing should be absorbed, especially with a head on collision with a softer target such as a building rather than a mountain.
Im assuming that the blackboxes were designed to handle a maximal catastrophe such as a direct impact to a mountain, but Im just assuming here, just broscience.
We do have a list of damaged blackboxes, but damaged is damaged, the government claims they never found them in NYC.

So we can say they are nearly indestructable, but usually when they are damaged it wasnt because they were vaporized from existence. They get damanged and data is unusable, but you still have the blackboxes. When the blackboxes are missing, the entire plane is missing along with all the passengers, and we do know where unfortunately that/they all ended up.
Anyways, still think the US government has them and they were just fine.
