    Re: Etymology of "loom"?

    An example occurred on the evening of April 26, 1977, when the residents of Grand Haven in Michigan looked west over Lake Michigan and saw city lights.   The city of Milwaukee, seventy-five miles distant, is geometrically well below the horizon and out of sight from Grand Haven.   An observation of a blinking red light convinced the viewers that Milwaukee was the city-above-the-lake:   An ingenious observer timed the blinking and called someone in Milwaukee to find out what it could be.   His measurement agreed with the frequency of the flashing red light beamed eastward from the entrance of the Milwaukee harbor.  Weather Service records for that time showed a strong temperature inversion over the lake[i]
