Sorry, I'm dense. I had previously (months ago) read the above rationale. But it (the question) still festers. Just how do you do a restart after the rocket has been released and left the pad. Or do you mean that it (the IRS software) could not sense exactly when it had been released from the pad? _______________________________________________________________________ Robert S.
