An additional United States Air Force C-17A Globemaster III, identified as 01-0186 with call sign RCH623, departed CEIBA, Puerto Rico, within the past hour. The departure follows earlier observed U.S. Air Force transport flights into Puerto Rico, including a C-5M Super Galaxy and another C-17A, which were tracked between 3:01 PM UTC and 4:01 PM UTC on September 12th. The latest flight information was shared via social media, noting the aircraft's departure from CEIBA, Puerto Rico. This activity occurs less than 12 hours after U.S. Marines arrived at the same location from Corp Air Station Yuma. The specific purpose of these ongoing U.S. military transport operations in the region has not been officially disclosed by U.S. authorities. This development comes amidst broader regional observations, including the recent docking of the Dutch Royal Navy frigate HNLMS Van Amstel in Curaçao and reports of Bolivarian military aviation F-16 activity near Maracay, Venezuela. These events have contributed to a heightened sense of military observation in the Caribbean.
