This is not the first time Morales has had an incident of this kind, since in December 2009 the plane of the president of Bolivia registered a technical failure when traveling to the city of Sucre (south) and had to land emergency at the airport from the central region of Cochabamba.
This failure in the hydraulic system forced the pilot of the presidential ship to land at the Jorge Wilstermann International Airport in Cochabamba.
In June of that year, the president was also forced to suspend his participation in the summit on the global crisis in the United Nations (UN) because his aircraft suffered a breakdown that was later repaired.
