Quoted for truth. "Everyone" expected him to stick the first barge
landing. And the second. And the third. Yet the times he didn't and
their predictions were wrong have already gone down the memory hole.
As Bill correctly points out, there's good reason for healthy skepticism.
(Not the least of which is the track record of a very complicated and
"sporty" landing sequence.)
