A greenish light lit up the whole area.

In approximately 1960 or 1961 (I was 14 or 15 years of age), I was laying on the floor of our living room watching TV in Carrollton, Texas.  The drapes were open onto the patio.   The glass area was approximately 22 feet. It was shortly after dusk.  My mother was there too. 
I saw a green glow light up the whole outside.  It stayed light for about one minute and then was gone.
A neighboring family (2 adults and 2 children) was up at their trailer at Lake Texhoma  (near Tanglewood and Lowe’s High Point) on this same night.  They were sitting outside and saw the same greenish glow. 
 A few minutes they heard and saw jets fly over.  The jets were from Perrin Air Force Base, which was located outside of Dennison, Texas.
Witness indicates that the date of the incident is approximate.  PD
