Two-thirds of downtown is plunged into a blackout that lasts more than five hours due to moisture in a power plant switch gear box.  The blackout began at 4:37 p.m. and was not resolved until 9:52 p.m.  An elevator operator was stranded in a downtown elevator, a man crashed his car through the window of a furniture store and an elderly man broke a hip falling down some dimly lit stairs.  No other injuries were reported.
