HONOLULU — Two Pennsylvania men, including one from Philadelphia, are among 12 Marines who are missing in Hawaii after two helicopters crashed off of Oahu Thursday, 6ABC reports.

The two heavy-lift helicopters did not return to their Kaneohoe Bay base after a training mission that night and a Coasr Guard helicopter and airplane spotted debris a few miles off the shore a few hours later. On board were four officers and eight enlisted men, the Marine Corps Times reports, and it is unknown if the two helicopters collided or something else caused them to go down in the sea.

Capt. Brian T. Kennedy, 31, of Philadelphia, as well  as 25-year-old Sgt. Adam C. Schoeller of Gardners, Pennsylvania were among those onboard.
