But some updates are better. About 5,000 FEMA staff were on the island prior to landfall on Sept 20. By Sept. 25, FEMA had over 10,000 people in Puerto Rico. Army Reserve and National Guard troops flew in from all over the country. Over 2,600 were deployed within a few days of the hurricane. Logistics ships, shipping barges and a hospital ship were on the scene or en route, bringing millions of meals and bottles of water, generators, cots, diesel fuel, medical supplies and other commodities. An "air bridge" was established at St. Croix, and began flying critical supplies to Puerto Rico as soon as it was possible.
