The Crash Site Debris Recovery Mobile Application is a prototype Windows Phone Application designed to assist crash investigators, first responders, and clean-up crews to locate aircraft crash debris in ground impact crash situations. The application, using a debris trajectory formula, the GPS location of the mobile device, a geoprocessing service, and user-defined variables of the affected aircraft and its crash characteristics, projects an estimated area of high debris concentration. In testing, the application has shown to be promising in furthering the development of mobile applications for use in airplane crash events
