I looked at both NOAA and DMA charts, but couldn't find the lat/long indicated
for airports.  I did find on the Missouri state aeronautical chart an airport
directory which listed lat/long for each airport in degrees and minutes.  Since
most runways are less than a minute long, these lat/long notations are too
vague to determine if they refer to the tower, radar, or what.
