Collapsed Structure Rescue Class 2006

 

divider line

Overview

During the week of May 15-20, 2006, the NASA Ames Disaster Assistance and Rescue Team conducted its annual advanced Collapsed Structure Rescue Class.  It was a six-day ~70-hour class.  This year, 27 students were selected from the hundreds of students that want to go through the class. All participants were selected based on experience, knowledge, and skills. Students came from as far away as Alabama and North Carolina with the majority coming from the eight California US&R task forces. The participating rescue specialists are typically considered to be some of the best in the country.
