We'll get the data to the committee, but I'm just kind of hypothesizing here. My sense is the number right now is higher than it was in the past, given that we've never had such a demand for class B folks. This is the challenge: operational tempo, the baby boomers kind of moving ahead, and retention issues, all of which have led to a higher number of class B personnel on one-, two-, or three-year contracts. There are probably more than there have been in the past. We'll get you the data to confirm that intuition.
