JOINT BASE PEARL HARBOR-HICKAM, Hawaii >> A team from a military command that searches for and identifies Americans missing from past conflicts is back in Alaska to assess a historical aircraft wreck site.

The team from the Hawaii-based Joint POW/MIA Accounting Command returned to Alaska on Wednesday.

An Alaska Army National Guard helicopter discovered what appeared to be an aircraft wreck site in the Knik Glacier area last June while conducting a routine training mission.

JPAC and Northern Warfare Training Center personnel collected possible material evidence and possible human remains from the glacier shortly afterward. JPAC hasn’t yet identified any of the remains.

The Alaska Command watched over the site to ensure its protection and keep an eye out for the surfacing of additional evidence. The commands launched a follow-up mission after the debris field resurfaced.
