1949 Lackland AFB, TX. Lights racing across the sky & making 90 degree turns on a dime.

While stationed at Lackland AFB in the fall of 1949 I had just completed 13 weeks Basic Training while waiting final assignment. I can remember shooting pool with fellow airman at the recreation center one night when someone called us outside to check out the UFOs.
 At first we were standing looking at lights racing across the sky from horizon to horizon.  Sometimes there were 3-5 at the same time.  They would make 90 degree turns on a dime and accelerate at a tremendous speed.  We were all baffled at the speed and maneuverability that the objects were able to make.  
I estimate 20-30 people witnessed this event with me including officers and pilots.  Some of them contacted the flightlines and eliminated to possiblity of the lights being weather ballons. 
Some of the pilots estimated them to be at 20,000 ft. or higher having a unbelievable rate of speed for being so high.
There was never any audible sound heard.
We ended up laying down on the grass watching them for about 1-2 hrs.
I heard the flightlines made repeated calls to Wright Patterson AFB throughout the duration of the event.

The date of the incident may be approximate, although the witness does not indicate that fact.  PD
