In this Nov. 9, 1965 photo, the view from the 52-story Prudential Tower in Boston, Mass., shows that not all parts of the city were plunged into darkness during the great northeastern power failure, fifty years ago. The John Hancock Building, center, Charlestown Navy Yard at left background, Boston Airport at center background and the South Boston Naval Annex at right all had emergency back-up systems in place and are lit. Copley Square is seen in foreground. (AP Photo)
