Many geographers have used the example of New York and Manhattan to
exemplify American urban phenomena and extremes. Cliche questions such as
"When will Manhattan Island begin to sink?" or "What would have happened
to the New York skyline without the elevator or the telephone?" were
widely popular in urban geography classes. Thus, it is not surprising that
within the first month after the terror attack a discussion ensued on the
future of the city, urban concentrations and dispersion, the skyscraper
and urban life.
