Well, I wrote a long article in response to yesterday's anonymous comment claiming that there were no extra GPS satellites involved in the SBAS system. It linked to plans, pictures and launch timetables for SBAS GEO satellites in Europe, India and Austraila. It quoted from the AIP, the FAA and the ESA. And it concluded triumphantly with a picture of a GEO satellite. It completely soothed the initial sense of guilt I felt when it was implied that I had given out incorrect information. And then Blogger ate it, saying on its status page, "We will also be down for about 10 minutes right now to reboot some servers."
I'm not rewriting it, and I'm ticked at Blogger now, for wasting my time so I'm not posting anything more until all my mammals are up to date.
