Mr. Thuan Chau, Defense POW/MIA Accounting Agency (DPAA) Isotope Mass spectrometrist, and Ms. Lyndia Low, DPAA Isotope Preparation scientist, give a presentation to Aliamanu Middle School students during a visit to Joint Base Pearl Harbor-Hickam, Hawaii, Feb. 10, 2023. DPAA consistently holds education tours both to engage with the local community and to educate students on DPAA identification and recovery operations. It provides an extra avenue to share the DPAA mission to achieve the fullest possible accounting for missing and unaccounted-for U.S. personnel to their families and our nation.
