evacuation. as you know, david, we were still in the process, before there was a need to do a non-combatant evacuation, we were still in the process of a drawdown at the airport, the previous plan, by the end of the month. some of the troops that flew home yesterday were in that tranche. they were very much a part of the original drawdown plan. admiral vasely saw fit that there was some others that he believed that he didn't need there at the airport anymore even though they had flown in with the plus-up for the neo. these are headquarter staff personnel, maintainers and other enabling forces who either had completed their mission and were already scheduled to go, as i said, even before there was a non-combatant evacuation and others who admiral vasely determined their mission was complete, he didn't need them
