The crash mags have made a "welcome" (if I can use that word) reappearance in the last year. They never truly disappeared, but a massive back-log built up - I think it was almost 3 years between issues, which I think can largely be ascribed to the continual churn between DASC / DARS / MAA and the length and complexity of SIs. Whatever blockage did exist has evidently become un-blocked because they are gradually catching up. It still seems to be a few months between SI report and crash mag, though, presumably because whichever SO3 gets the task of distilling the report has got a bazillion other things to do.
