https://en.wikipedia.org/wiki/Magnetic-core_memory:
"For example, the Space Shuttle IBM AP-101B flight computers initially used core memory, which preserved the contents of memory even through the Challenger's disintegration and subsequent plunge into the sea in 1986.[27]"

Just another reason to appreciate this forum - fascinating subjects.
