La Caída del vuelo 901 Done by the Costa Rican newspaper La Prensa Grafica, this is an interesting website about the crash of Aviateca Flt 901 (a Boeing 737-200), which occured on August 9, 1995, and remains El Salvador's worst aviation accident. The aircraft was a victim of Controlled Flight Into Terrain (CFIT) into Volcán Chichontepec while on descent into SAL and deviating around weather. Fascinating pictures, as well as a 15 minute audio recreation of the flight. Unfortunately for non-Spanish speakers, most of the information is in Spanish.
