There was a story posted to Usenet yonks ago about a minicomputer (PDP-8?) 
being used for nuclear testing.  The last test involved the box inside a 
truck, parked on top of the hole.  Truck flies up into the air, but the 
core memory survived intact, was retrieved, and plugged into another box 
and all the data read out.  Try doing *that* with solid-state memory :-)
