To: Public Affairs Officer, AAI-5
JAL flight 1628, on November 17, 1986, and supplements discussions we have
had regarding what has been referred to as "split images",
We concur with the interpretation provided to you by the Alaskan Region
Air Traffic Division.
The attached Analysis of Uncorrelated Primary and Beacon Targets by Dennis
Simantel covers the subject in more detail, and addresses the questions
raised in your letter.
Paul, I appreciate the team approach you have taken to more fully
understand a complex issue. The issue is an excellent example of how
"interdependent" we are. If we can provide any more information, please
do not hesitate to call.
