Description
The results of the airborne observation of ATV-1 resulted in excellent data about re-entry break-up 1. The triangulation of the video data showed experimentally the distribution of debris on ground and the spectral data allowed some insight into the destructive entry process1.

The High Enthalpy Flow Diagnostics Group participated since then in all airborne re-entry observation campaigns of entering object and I was the science lead of the planned observation campaign of the last ATV-5, a mission which was cancelled at the last possible moment due to malfunctions aboard ATV-5 [2].
The paper gives an overview on airborne observation missions. It highlights challenges, preparation procedures and give an outlook into what data sets can be achieved. Recent results from missions I participated, WT1190F und CYGNUS OA6, will be presented as well. The paper gives an outlook of what is required to be experimentally simulate these effects on ground and how future events can be implemented in order to develop a database for re-entry break-up. The outlook will go into what can be drawn with respect to meteorite analysis.
