To be fair, he was ragging on the costs, not expressing glee in the mishaps.
I'm not that happy with the price tags on some of our defense systems, either. Procurement often becomes a political/industrial circle-jerk, with more attention paid to goodies being passed into congressional districts than real defense needs.
I long ago lost count of weapons systems and projects that develop a life of their own, sometimes even when the Pentagon itself says they're not necessary.
