The O3K recommendations are years behind schedule but that is due to a lack of prototypes.  However, the O3K Coding and Synhronization protoypes are almost complete (>95%); the O3K Physical prototypes are about 50% complete.  This Blue Book is relying on the resources of agencies not tied up in the O3K recommendations and prototypes.
