Introduction: A brilliant fireball was seen by many eye-witnesses in Austria and Germany on April 6, 2002, 20:20 h (UT). The associated meteorite fall was well documented by the European Fireball Network (EN). Based on the EN photographs the meteoroid orbit and the impact area were calculated by Spurny et al. [1], which finally led to the recovery of a single stone of 1.75 kg in July 14, 2002. ...

Abstract Fireball networks are used to recover meteorites, with the context of orbits. Observations from these cover bright flight, where meteoroid is luminescent, but a fallen meteorite, observations must often be predicted forward in time ground estimate an impact position. This dark-flight modeling deceptively simple, there hidden complexity covering precise interactions between meteorite an...
