BRL-CAD BRL-CAD BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system. It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools. The entire package is distributed in source code and binary form. Although BRL-CAD can be used for a variety of engineering and graphics applications, the package's primary purpose continues to be the support of ballistic and electromagnetic analyses. In keeping with the Unix philosophy of developing independent tools to perform single, specific tasks and then linking the tools together in a

Secure Flight has been blocked by Congress until the government can prove that the system can pass 10 tests for accuracy and privacy protection as follows: On July 21, 2006, TV station ABC 7 in Denver, Colorado, released a report, citing air marshals that were using a quota system of reporting one person per month as a requirement for advancement. These reports are filed as Surveillance Detection Reports: it is unclear how many such reports are required on a person to place them on the watchlists.
