This is kind of what I thought, too. It must be an emergency strip. I bet that, in a pinch, they could get a Mirage in and out of there. It could also have been for in case they needed to evacuate Rio Grande, or even to evacuate TO Rio Grande. Like if Buenos Aires was getting hit by the Brits. It's not like there aren't a few people in Argentina with evacuation experience. Realizing what I was riding on when I got about halfway down it, I was, like, huh? Was Eisenhower here?
