That was an intriguing sight!
As our flight wrapped around San Antonio anticlockwise to approach the airport, I spotted what you see in this picture while looking out of the window. The Delta map showed we were due north west from the city.
At first glance, it looks like a small airport with a single active runway (and a feeder one). Then the details become a little more interesting. There are no buildings around it!! In fact, it appears that there is no concrete or asphalt. It is just cleaned and leveled ground.
First I thought that it might be used for crop dusters. But it seems too long for crop dusters. Plus there is not a single plane standing there. There are no hangars. The airplanes could not have been towed away anywhere since the only connection into the runways are a couple of narrow dirt roads.
Perhaps, an airport under construction? A private airport? But there is absolutely zero construction machinery around.
An abandoned effort to build an airport?
Would anybody know or venture to guess?
