This repository serves as an archive and documentation site for FOIA materials related to the MU5735 aircraft incident investigation. It contains PDF documents, email records, FDR data in CSV format, and visualizations of flight data. The repository does not perform active data processing but preserves and presents source data for analysis. The most notable technical component is an interactive FDR data visualization built with vanilla JavaScript that reads CSV files directly and provides filtering, zooming, and multi-chart display capabilities. This visualization component demonstrates good separation of concerns and could be reused for similar time-series CSV datasets with minimal adaptation.
