We describe a method for the automatic assembly of aviation safety cases by combining auto-generated argument fragments derived from the application of a formal method to software, with manually created argument fragments derived from system safety analysis. Our approach emphasizes the heterogeneity of safety-relevant information and we show how such diverse content can be integrated into a single safety case. We illustrate our approach by applying it to an experimental Unmanned Aircraft System (UAS).
