[BC] Bad tower design

[towers at mre.com]

On flanged intersection couplings, that's standard practice.

> KFI's replacement tower -- 2008, first (failed during erection) and
> 2008, second (erected successfully) -- has bolted joints for the
> cross-bracing. Two bolts in each brace where it meets a welded flange
> on the vertical member and two bolts where the cross-braces
> themselves cross.
>
> Reading from a description of the erection procedures, the bolts
> which connect the vertical members are intended to have the nut on
> the top, and the bolt on the bottom, so should a bolt fail it will
> drop free of the flange and thereby allow for inspection from the
> ground.
