   From the LOS ANGELES TIMES, 12 September 2001, pg. A4:

   'The technical term is progressive collapse--the slang term is pancaking," said Ron Klemencic, president of Skilling Ward Magnusson Barkshire, the Seattle firm that engineered the World Trade Center.  "What basically happens is that one floor falls on top of the floors below it, and with one floor falling on top of another there's no way to stop it."
