Salvador Allende, Pablo Neruda, Indira Gandhi, Haile Selassie, Norodom Sihanouk, Yassir Arafat and the 14th Dalai Lama are among the personalities interviewed by him in his time as a reporter.

Another program that he worked for was A la caza del tesoro ("Treasure Hunt"), presented by Isabel Tenaille: Miguel traveled by helicopter somewhere in the world following the instructions of a contestant who was in the studio in Madrid.

The Ruta Quetzal was created suggested by the King of Spain in 1979, with the aim of strengthening the Latin American Community of Nations in the young people between 16 and 17 years old among all Spanish-speaking countries.

Since 1979 the route has covered more than 20 countries: Brazil, Peru, Ecuador, Venezuela, Bolivia, Mexico, Guatemala, Dominican Republic, Paraguay, Honduras and Costa Rica.

Besides purely academic activities they are also workshops on new technologies, computer, television, journalism, photography, astronomy, diving, marine science, music and other subjects, as well as talks and discussion sessions on "Development Cooperation".
