...Dynoman! I'm pretty sure that the document does not refer to any sort of satellite system, but we may have discovered another piece of the ISINGLASS/RHEINBERRY puzzle. I wonder if the "BG" designation refers to a boost glide vehicle? And could these be the aircraft redacted from the timeline...
...design a replacement high altitude reconnaissance aircraft with a speed of Mach 4-5. It was identified for the FY64 under the program name ISINGLASS. This work appears to be a precursor to the McDonnell Douglas effort to develop a Mach 20 vehicle, according to the timeline. Unfortunately, no...
Note that this document is not ISINGLASS. ISINGLASS was canceled by that time. On page 2 it states that this study should take into account earlier work, including work done on ISINGLASS.
There are several words deleted at the bottom of page 1 and the top of page 2. It is possible that the...
...i.e. McDonnell Douglas (now a part of Boeing). I noticed when I sent a FOIA request to the CIA they omitted the "manned drawings" of ISINGLASS, leading me to believe that their interest in boost-glide vehicles surpassed the stillborn ISINGLASS project.
The other data I have is from NRO and...
...B-52 launch? I don't remember.
If not, is our only source for B-52 launch that CIA Oxcart history, with its rather confused Rheinberry/Isinglass reference?
It still seems to me that an XLR-129-powered vehicle is just too big for a B-52 and that Isinglass more likely took off vertically...
...conducted a study for a boost-glide vehicle, known as the Advanced Aerodynamic Reconnaissance System, that followed the cancellation of the ISINGLASS project. Additional documentation shows meetings with McDonnell Aircraft Co., concerning this new reconnaissance study. Money was sought for...
...looks like they have applied 1980's and 90's stealth techonologies (e.g. faceting and leading-edge-alignment) to the what may have been the ISINGLASS configuration (if as you say they were inspired by the ISINGLASS vehicle).
The distinctive BWB fuselage with 'bulbus' aft section, twin...
