[TowerTalk] Yagis and Rivets

[alsopb]

Brad,

My knowledge is dated.  My understanding is that most structural
rivets on an airplane are not the bind pop rivet type.  They are
flattened on both sides.  I would certainly trust them.  A comparison
of pop rivets to them doesn't seem valid.  I also believe that the
QC/petigree of parts, installation tool, inspection and installation
instructions should be better for the aircraft stuff.
