Part of the joy of having books is to be able to comprehend what is written in them. The one you allegedly have points out very clearly what happened to the signal, or did you happen to miss that entire chapter?
Allegedly is quite right. Patrick has routinely lied about owning, and having read, books related to Apollo, when it is painfully obvious that he is simply grabbing bits that Google Books will display for him.
Unlike the prolific-but-inept liar Patrick, I actually
own a copy of the book. I am looking at it right now.
