The ones I briefed this morning are actually all primary. They are the ones that are on continuous standby--half-hour or two-hour posture. The secondary ones don't maintain a full standby posture. Their primary duty is in support of military flying operations and military activities, but they have SAR capability and SAR techs to respond, and often we will use those resources.
As you may recall from my previous statements, the first responder, the vehicle, the search craft that is closest to the incident site may be the best choice. And in a lot of cases these aircraft participate as some of the front-running SAR resources.
