Also the 900-kilogram steel plate cap for the test shaft of the Pascal-B nuclear test.
Dr. Brownlee had estimated that the nuclear explosion, combined with the specific design of the shaft, would accelerate the plate to approximately six times escape velocity.
Granted…
The plate was never found, but Dr. Brownlee believes that the plate never left the atmosphere, as it may even have been vaporized by compression heating of the atmosphere due to its high speed.
But we now know much more about meteorites, including that the heat of re-entry will still have them arriving at the ground with a cold interior.
