Senior Airman Daniel Van Stone, 28th Civil Engineer Squadron emergency management technician, sets up a weatherpak during an antiterrorism exercise at Rapid City Regional Airport, S.D., March 12. The weatherpak extracts local weather information from the air to provide the mobile emergency operations center with the most up to date weather information. Ellsworth Airmen teamed up with their civilian counterparts during the exercise, in an effort to develop a working relationship and become familiar with the policies and procedures of each other.
