CLEARED FOR LANDING — A twin-engine Bell 412 helicopter is lowered into Heritage Park at the National Museum of Nuclear Science & History on March 24. The aircraft joins the museum’s fleet after a 30-year career supporting the NNSA Nuclear Emergency Support Team, providing radiological surveillance at presidential inaugurations, Super Bowls and political conventions. Sandians have contributed technical expertise to NEST’s mission throughout the program’s history. (Photo by Lyndsee Cantly, National Museum of Nuclear Science & History)
