Schirra and Scott Grissom

I've been scanning through three years of banter between Scott and all
of you, and I have yet to find the original statement Scott made about
Schirra. Obviously I'm not putting the right words in the search
engine; I've tried all combinations of Apollo One, Scott Grissom,
Schirra, and sabotage. Would somebody just post the reference,
please? Thank you.
