THE PACIFIC OCEAN—After years of warnings from Congress, the island of Guam has finally capsized, according to several Department of Defense officials familiar with the matter. Satellite imagery confirmed that the island disappeared into the Pacific Ocean early Thursday morning. There were no survivors.

Senior defense officials say the island's inversion was the result of poor management by the Navy and Air Force.

“What happened this week was that the Air Force aircraft that are usually on the north side of the island were away on a training mission,” said a senior Navy civilian, speaking on condition of anonymity because he still didn't believe this had actually happened. “At the same time, a destroyer squadron docked at the naval based on the south side of the island.”
