"Night
Air Mail Service" was launched
on January 30, 1949 in India by Rafi Ahmed Kidwai to improve the postal service. Air Mail Service was introduced when Railway Mail and Motor
Mail had reached saturation point.
Since
space was a premium at daytime flights, it was decided that air mail would move
at night and this had the added advantage of making overnight delivery possible
in what may very well be also the world's first example if not one of the
earliest examples of a hub-and-spoke operation. Under this system, the four
main cities of India also happened to form each of the four corners of a
diamond- New Delhi to the north, Bombay to the west, Calcutta to the east, and
Madras to the south. Connecting these cities was a central location at the city
of Nagpur in central India.
The
system was quite simple- letters postmarked for overnight air mail were
delivered to each of the corners of the NAM system in the evening and loaded on
aircraft. These aircraft, all then flew in the first part of the night to the
central processing and sort facility at the Nagpur Airport. Mail would be
offloaded and sorted to waiting aircraft that would return to their origin
airports in the second half of the night. The following morning, the mail would
be delivered- a speed and convenience not only unheard of an India's business
environment of the day, but probably in just about any business center
worldwide in 1949! For an aircraft like the Douglas DC-3 that was ubiquitous in
those days, each leg would take about four hours, making overnight delivery
possible. To facilitate the sort process, any aircraft leaving any of the
cities already had the mail sorted and stowed aboard in batches, minimizing the
ground sort and loading time at Nagpur.
The
Indian Night Air Mail Service ran continuously until 1973 (ironically when
Federal Express launched its overnight package delivery service). The low
postal rates provided by the Indian government were cited as not being enough
to warrant continuation of this historic service. Various attempts were made up
into the 1980s to restart the NAM, but were never profitable enough to last
long.
