Date:
August 1947
Location:
Holloman AFB, NM
Francis
Ridge:
The radar is modified to track
objects at very high
altitude. They aim the antenna straight up and pick up a target at 200
miles
up. The report leaks out, Project SIGN sends two high-level
investigators, but the prime
witnesses are conveniently not available. For the full report
documents, see
links below. Not found in the original Project Blue Book unknowns, this
incident IS
listed in the updated list by Brad Sparks: "AMC Watson Labs
Project Mogul engineer Rosmovski and communications
officer Lt. H. G. Markley tracked a stationary target at 200 mile
altitude using a modified
CPS-4 radar aimed at 70-degree elevation." (FOIA, Loren Gross, Aug-Dec
1947 SUPP p.28.)

Lt. Robert G. Markley:
During the latter part of August, 1947, this organization was carrying
on several test runs with a modified SCR-270 at this base.....object
was traveling at an unprecedented rate of
speed and appeared to be several thousand feet over the top of the
Sacramento mountain range, traveling in horizontal flight south to
north......have been other times when manning the M-2 Optical
tracker, that I have seen round or flat-round objects that were
unexplainable.
Brad Sparks:
......the CPS-4 radar had been specially "modified" for
the specific purpose of extending its 90-mile range to some 250 miles
and to point it straight up into outer space to look for targets -- and
then it did exactly what it was specially designed to do.
