Could someone please summarize the status of observations and non-observations of KH 11-8, USA 86 and USA 116? As I understand it, 11-8 has definitely been identified, as has one object which may be USA 86 or 116 based on its orbit. Is this reasonably correct? Also, how firmly can it be said that there is only one, rather than two, objects in orbits compatible with USA 86 or 116? If USA 86 has been replaced, that seems to be quite a short lifetime in terms of recent KH-class vehicles. Were there any signs last year that it was behaving abnormally?
