In April we marked the 50th edition of the Confidential Reporting on Structural Safety (CROSS) newsletter (page 24). The first newsletter was published in November 2005 with brief comments on a number of short reports under the headings: Near misses, Collapses, Design issues, Building control, Engineers on site, and Fixings. CROSS had started a short while earlier on a six-month trial basis and we had no idea if the project would take off . Since then it has grown and is now the model for versions in other countries. The core topics have remained remarkably similar, showing that lessons must be continuously re-learned so that safety culture can improve. Many thousands read the newsletters around the world and the number continues to grow.
