I feel it's worth noting that if you are parked right there at the exit you are in perfect position to watch for a plane landing a few hundred yards right in front of you. Do any websleuths have knowledge about cameras recording activity after hours at the airport?
No, you do NOT have a good view of planes in and out, and you can't actually see any runway from SWFA anyhow, or any planes that might be approaching or departing from the other end, as there is a hill elevation between SWFA and the airport. Sitting at that exit, all you see is a grassy hill.
But I doubt that tiny airport was used (or usable) that night of the murder anyhow, due to the heavy rain.
