Either the box was right next to any detonation aboard the plane or they are lying.
The box would have to hit the water at mach 20 to damage it.
“The box would have to hit the water at mach 20 to damage it.”
- Surpisingly, they are rated at an impact slightly above 300mph. I assumed it would be much more but looked it up.
At mach 20 the box would be nothing more than a pool of liquid (or a mist of plasma). And that is before it hit the ground or water.
They’re good to a shock of 3,400g and a temperature of 1,000 degrees C.
