It was a total gost to our radar.

1978, UFO incounter with 'B' Battery 1/43rd ADA Alaska.
A orange red light, about 2 feet wide, came down from our ceiling and at a slight angle.  This wall of light moved slowly as we followed it out all the way out the front of the building.  We were ordered to stay inside but did not.  
When we got outside and looked up, we seen a UFO over our heads, about 50 or 60 feet above our MTR radar.  It hovered above us and made no noise what so ever.  It disappeared in a direction toward Anchorage at a speed that was a blink of an eye, and again no noise or sonic boom.  
We were on hot status and it never showed up on our radar.  We went into lock down and the 1/72nd base commander had every witness sign a form what you seen you did not see. 
Three of our soldiers went AWOL becauses they refused to sign the confidentiality form.  All three were labeled subversionist and recived BCD's.
I have lived with this for many years, and now cancer will relive me of this memorey soon.
The source of the report provides a name, but no contact information.  We are unable to contact him.  PD
