Isn't that frelling repugnant? It's one thing to joke about your own mistakes; hell, I consider it a very good thing. But I believe joking about mistakes that have gotten hundreds of people killed are another matter. Inappropriate at best, despicable at worst. You can probably guess which side of that coin I come down on.
