The Isinglass / Rheinberry concept was considered to be superior to spy satellites in a number of ways, including rapid turnaround time and quick response capability.
This does not include the 1950 and 1960s budgets for the Dynasoar, ISINGLASS, Rheinberry, and any 21st-century spaceplane project which might emerge under Falcon.
As there was little funding to be had from the CIA budget, McDonnell developed the aircraft using its own funds, although technical support gleaned from Oxcart was supplied by the CIA . The McDonnell Isenglass / Rheinberry proposal's shape remains classified, although it has been described as being similar to the Space Shuttle, albeit much reduced in size.
The first engine to include an expanding nozzle appears to be the Pratt & Whitney XLR-129 . The XLR-129 was developed in order to power a McDonnell Aircraft boost-glide aircraft design that was entered as part of the Project ISINGLASS ( or RHEINBERRY ) study looking at follow-on designs to replace the Lockheed A-12 that was just entering service.
