Group /Category 9 - Radar Case

Bill Chalker:
The IUR March/April, 1986 (letter) and my response in Sept/Oct. 1986 issue address issues re radar aspects in the Chilean case.  I have since tracked down my informant again and he confirms the radar aspects as valid, per my follow up letter comments.

At 12:43 A.M. the radar officer reported a long-range flying contact. A minute later the "contact" was at 400 miles. Because of the "object's" speed, the operator suspected a malfunction in his equipment. In the next minute the contact was approximately 150 miles away closing from 331 degrees of true north. But the operator and officer in charge during the late night duty (an officer of second-class rank) speculated that the contact was a "plane flying southeast" --but at 213 miles in a minute: 12,780 mph!
