SAS
One month delay after first flight is normal for instrumentation refinement.
Six month delay points to need to improve parts.
Two year delay looks like a major problem which requires significant design changes.
Since the 97 was to be used for SB1 risk reduction, it explains the major schedule slip of SB1. The question is how many other problems will be encountered growing the concept another factor of three?
