Regarding R.J.Smiley's post on what the judges look for, one item really
bothers me about what the judges look for. To wit:

"All bolts should be head down and.....". If that's the case, then Rockwell
and Boeing (and many other aircraft manufacturers of note) have been doing
it wrong for a lot of years!

Unless I misunderstand the sentence, bolts are installed "head down" only in
special circumstances - and then only if there's no other way. The idea
being that if the nut somehow fell off, you'd still have a chance that the
bolt itself would remain in place (gravity sucks, y'know), rather than fall
out and let what the bolt was connecting separate.

I believe there was a minor "misspeak" here - but what do I know.
