It was 60s or early 70s. NiCds resistance goes down as temp increases, and
the self discharge goes UP. At a critical temp, the dischare current is
enough to heat the cell enough so the temp continues to increase...
The explosion happened because some one removed a cell to try to fix the
problem of the batteries going flat in short haul ops... I read a reference to
it in the mid 70s, never seen the original report. NY-Florida perhaps, but
no promises on that.
