An additional quote from the "letter never sent" (except to the OIG):
Bull! It is true that a thorough inspection of the cotter pin installation can be accomplished after the sealant is applied—but only if you believe in Superman and also believe in his fabled X-ray eyesight powers, and only if you could then pry him away from the massively more Earth-shaking duties he would likely be doing now if he existed--such as trying to find Weapons of Mass Destruction in Iraq with those X-ray eyesight powers—just to try and use his "superpowers" to instead peer through the thick, opaque globs of sealant to inspect a little old cotter pin. However, "Superman" may pull away from his search for WMD in Iraq, even if that search for WMD was at GWB’s urgent request, if he knew the truth--that that one cotter pin’s thorough inspection may be the difference one day as to whether hundreds of people at one time live or die, or perhaps get to swim with and within sharks as their last experience of their lives when an engine "departs the plane" halfway through their ETOPS flight over the ocean.
