JP 3-50 National Search and Rescue Manual Vol I - US Navy

Actual search progress can now be monitored using the search
area plot, and findings readily plotted. Figure 8-6 shows a
typical search plot.
826 Search Interrogation
A. Appeals for information through press and radio, on scene
interrogation, or interviews with local population may lead to discovery
of the search object. Land SRUs are often used as interrogation parties
or the nucleus of such parties. However, before assigning this
function, the SMC or IC should ensure that another SRU is readily
available for the search area.
B. Normal communication equipment and a portable tape recorder
will be adequate for interrogation.
C. Proper interviewing obtains pertinent information from
witnesses. Individuals seeking publicity, those with overactive
imaginations, or those who desire to help despite lack of information
should be interviewed with caution. Unnecessarily revealing factual
data to such a person may encourage "exaggeration". Leading questions
should be avoided. Try to eliminate false leads based on imagination or
power of suggestion.
D. Details are important. Information obtained should be given to
the SMC or IC at the earliest opportunity. Addresses and telephone
numbers of persons interviewed should be recorded in case more
information is needed.
827 Wreckage Precautions
A. Both motor vehicle and aircraft crash sites can pose hazards to
searchers from wreckage, chemicals, explosive munitions, or radiation.
An aircraft crash site may have each hazard spread over several miles
following impact. Appropriate safety precautions should be observed.
