Was anybody monitoring/listening on 216.98 mhz to the NAVSPASUR echos when the shuttle went over north central Texas? Multiple echos? The Lake Kickapoo CW transmitter was almost directly underneath the apparent breakup. The apparent breakup may have been east of the NAVSPASUR illumination fan, but there is always a possibility of late multiple doppler sequences. Since NAVSPASUR is always "on", and signal reflection is passive, it is possible to capture doppler echos. A few info links for NAVSPASUR reference: For NAVSPASUR, see: http://science.nasa.gov/newhome/headlines/ast22dec98_1.htm and http://www.jump.net/~crossley/NAVSPASUR/how.html For signal samples: http://www.meteorscatter.net/msound.htm Search GOOGLE or whatever for "navspasur" and "wav" and etc references.
