I worked in the ordnance industry. We had to design warheads and electronics that could withstand 60,000g's for 20 milliseconds. These were used in "hard target warheads". Ones that had to penetrate a reinforced concrete bunker and still function properly. You can engineer things to with stand virtually anything. The physicist Lew Allen, in the 1950's experimented with getting steel balls to survive within the nuclear fire ball of an A- bomb blast.
