(at around 1h 6 mins) During the 1959 accident at the Intrinsic Field Laboratory, the door lock time mechanism uses a Nixie tube digit display. The '5' digit can be seen to be an upside-down '2'. This is a characteristic of Russian (or Soviet) Nixie-tube displays and therefore would not be used in a U.S. scientific facility.
