From ANIMAL PEOPLE, September 2001:
The animal dimensions of the September 11 terrorist
hijackings of jetliners and mass murders at the World Trade Center,
the Pentagon, and Somerset County, Pennsylvania, were as evident
as the search-and-rescue dogs sent to each scene to help find
survivors and remains, the bomb-sniffing dogs at airports whose
numbers suddenly seem all too few, and the many pets in transit who
were held overnight in air terminals when their flights were grounded.
Many stranded people probably wished they could hug a dog or
cat during the 30-to-48 hours before air travel resumed, and many of
the animals would have welcomed the attention, but there was no way
for anyone to make pet-sharing arrangements.
