Go-around - my first sighting

I was admiring an Emirates A330 on finals earlier today. It appeared to
be on the proper glide path (guaging from the earlier string of
aircraft). A mile out or so, for some reason, TOGA! and the aircraft
went into quite a nose-up attitude and climbed away, aborting the
landing.

This go-around happened on a clear wintry morning with little or no
wind. Hope the Cap'n doesn't lose his job, unless there was some other
reason like runway incursion )

Have you guys ever missed an approach and had to hit TOGA? And does a
go-around make its way as a pilot's log book entry?
