Overhead Air Traffic

So, late this afternoon, I was enjoying the weather, sitting in my back yard, reading.  Although it was daylight, the moon hung in the East. 

There is sometimes overhead air traffic, sometimes commercial airliners, sometimes military planes, especially very high over head, leaving con trails.  Sometimes, sadly there are the red Aerocare emergency airlift helicopters on their way to either University Medical Center, or Covenant Hospital. My house is 3-4 miles south of each hospital, and just a few blocks east.

Today, a whitish/silver helicopter came from the southeast, hovered north of my house but south of the hospital districts, and then, moved west.  Twice after that, the same or different but similarly shaped and colored helicopters came in from the southeast.  While that was happening, three times a very small plane or more than one very small planes flew north from the southeast, sort of arcing to the northwest, also towards the hospital district.  The plane was short, and had a stout wing span that seemed almost as long as the length of the plane. One time, the plane and a helicopter, now moving to the southeast, were on what looked like intersecting trajectories, albeit at different altitudes.

This was different for me. But for all I know, this is a very common air traffic pattern for this time of day in mid-Lubbock.   Hmmm.
