David L. Wilson has caught an error in the September column.
In the section discussing U.S. Air Force ALE addresses, the statement that McClellan (MCC) is still "using the same transmit and receive sites" is in error. The transmit site moved from Davis, CA to its current Dixon site in the early 2000s, after McClellan AFB closed.
Photos of the old site can be seen in this flickr album. It has since been completely demolished.
We regret this inaccuracy.
