Mexico: After the 1985 Mexico City earthquake, the Ministry of Foreign Affairs will deploy a plan used to aid civilians during the natural disasters in Haiti. As an emergency response the government sent three Hercules C-130 military aircraft carrying over 20 tons in supplies, as well as satellite communication devices, water treatment plants, electricity generators, and over 160 specialists in search and rescue, health professionals, and engineers sent to set up communications in Haiti. One of these airplanes, with 60 federal policemen, had to temporarily abort its mission, due to lack of space at the airport. The water treatment plant had to be returned to Mexico, due to lack of ground transport. The government also sent the Navy's amphibious lander with several thousand tons of aid materials and the hospital ship ARM "Huasteco" as well as additional aircraft.
