MEMORANDUM FOR Commander Task Group 7.4%
SUBJECT:
Radar Tracking of Sempling Aircraft for Pinea
1. This will sonfirm conversations held between Colensl Wignell,
Dr. R. Batsel and myself on the tracking plan.
The purpose ef provid-
ing for a tracking system is fundamentally to add plausibility that
the sampling mission was conducted in e straight-forward manner. It
will not be the intent, hewever, to try to indicate to the U.l.Obvesrvers
or to the press, that the tracking system is a Proof that the sampling
mission was in fact carried out as shown.
2.. To appropriately accomplish the radar tracking scheme, it is
requested that TG 7.4 provide a briefing on the radar system to the
observers on D-l or D-2 to familiarize them with the aysten ani equipment. As part of the briefing it would be desirable to have one of
the B57 B sampling aircraft make a take-off, fly a short pattern, ari
land so the observers can see how the system operates.
3.
On shot day, if the U.K. observers desire it, they will be
permitted totrack the sampling aircraft as they carry out their mis-
sion. Selected members of the press,should be allowed €0 be in the AOC
in the gallery during thie period. “he redars should be set for a range,
probably 150 miles, such that the planse in flight will not pass eff the
scope. All radars should be set up the same way. 4+ also would be desire
avle to plot on the large plotting board a contimous track of the courses
Loliowed by the aircraft froa take-off to landing.
&,.
We would apprreciate your coments on the above preposal.
