You can fly to Mariscal Estigarriba (call sign: ESG), but it's not any airline destination.
I still don't know what the status of the field is.
In 1999 I discovered an open hangar being build, but still empty.
There is a small station building (4 rooms) with fresh water and a radio to guide the occasional visiting plane.
One soldier at the gate.
Update: Around 2005 US marines were stationed here to increase political pressure.
