Some of the terms associated with the term "Huaira" indicate a relationship with wind:
Huaira: viento (wind).
Huairazo: viento fuerte (Strong wind).
Huaira-Cuichi: viento del genio del mal (wind of evil).
Huaira-Huañuy: viento de la muerte (wind of death).
Huaira-Mancharinapac: viento de todos los espantos (all ghosts' wind].
Huaira-Miu: viento del infierno [hellish wind].
In consequence, Huaira Bajo should mean a Low level wind, and I have read some kind of implication or connection with altitude sickness (hypoxia).
You are right in your reading the smuggling connection.
The City of Santiago del Estero, is located in an area close to Bolivia and Paraguay, and near the Andes mountains.
In years past [cannot say anything about the present times, because I don't know] smuggling was a growing industry there.
The authorities of the State of Santiago del Estero, thought that they could establish an airline using aircraft seized during smuggling operations.
Soon enough they found out the difficulty of operating such a diverse fleet, plus the costs associated with radial engines, and the airplanes were simply pushed to one side of the runway and left to rot.
I am showing two sets of pictures; the first one shows the C-46, the C-45 and the B-25J, and not visible, there was also a "Huanquero" which was an Argentinean designed and built airplane.
The second set dates to 1998, showing the B-25 already under roof.
There were reports that I found credible, a couple of years ago, stating that the B-25 had been scrapped.
Less than two weeks ago, I made contact with a guy in Argentina, who stated that as early 2006, the B-25 was still there.
Curiously, I just happened to mention this particular B-25 to a couple of guys at the Warhawk museum, last Saturday : )
I tried in the past, to get people interested in rescuing this airplane, but there were no takers.
Just in case, I know the guy who can do it, who has recovered several aircraft from South America.
If anyone is interested, please PM.
Lastly, I have altered the faces of the people in the pictures, because I do not have their permission to show their faces on the web.
