Central America is the bridge through which the biggest cocaine producers, Colombia, Peru and Bolivia, send the drug into Mexico.
Hundreds of tonnes of cocaine travel through Honduras, where a coup in 2009 is thought to have provided a window of opportunity for traffickers.
Communities are the effects, with suspected drug flights into the country having sharply increased from a handful in 2006 to more than 80 last year.
Most traffickers there are Honduran, but analysts say there is increasing evidence that they are managed by Mexican gangs.
