Thanks all for reply; I first thought it was Salinas, but it looks so much different when I was there in 1997! So that's why I had a moment of belief that it could have been a deployment to Galápagos Islands for exercise
The picture showed at least one dual, and I guess that this picture must been taken between 1985 and 1990, when Escuadrón 2111 had still eight aircraft left, but perhaps even more before?
Those where the days .....
Saludos a todo.
