Historical Search Planning Tools
Prior to SAROPS, SAR controllers in the U.S. Coast Guard used the Computer Assisted Search Planning (CASP) and Joint Automated Work Sheets (JAWS), which used dated search planning techniques and algorithms. More specifically, CASP was based on old computing technology and JAWS was taken directly from pen and pencil techniques for shorter durations of drift in coastal environments. Environmental data consisted of low-resolution (1-degree latitude/longitude grid) wind and current information that was applied every 12 hours. For most areas, CASP used monthly-averaged current values while JAWS used one wind and current value during the SAR case. Neither system was capable of accessing timely high-resolution wind nor current model output, which was a significant disadvantage since one of the main components that determine the accuracy of the drift solution is the presence of precise and accurate wind and current information for the given area of interest.

“Whether considered as a doctrine, or as an historical fact, or as a movemement, socialism, if it really remains socialism, cannot be brought into harmony with the dogmas of the Catholic church.... Religious socialism, Christian socialism, are expressions implying a contradiction in terms.”
—Pius XI [Achille Ratti] (1857–1939)
“You have riches and freedom here but I feel no sense of faith or direction. You have so many computers, why don’t you use them in the search for love?”
—Lech Walesa (b. 1943)
“My consciousness-raising group is still going on. Every Monday night it meets, somewhere in Greenwich Village, and it drinks a lot of red wine and eats a lot of cheese. A friend of mine who is in it tells me that at the last meeting, each of the women took her turn to explain, in considerable detail, what she was planning to stuff her Thanksgiving turkey with. I no longer go to the group.”
—Nora Ephron (b. 1941)
“Machinery is aggressive. The weaver becomes a web, the machinist a machine. If you do not use the tools, they use you. All tools are in one sense edge-tools, and dangerous.”
—Ralph Waldo Emerson (1803–1882)
