Abstract
On 8 October 2011, the Draconid meteor shower (IAU#8, DRA) was predicted to cause two brief outbursts of meteors, visible from locations in Europe. For the first time, a European airborne meteor observation campaign was organized, supported by ground-based observations. Two aircraft were deployed from Kiruna, Sweden, carrying six scientists, 19 cameras and eight crew members. The flight geometry was chosen such that it was possible to obtain double-station observations of many meteors. The instrument setup on the aircraft as well as on the ground is described in full detail. The main peak from 1900-dust ejecta happened at the predicted time and at the predicted rate. The second peak was observed from the earlier flight and from the ground, and was caused most likely by trails ejected in the nineteenth century. A total of 250 meteors were observed, for which light curve data were derived. The trajectory, velocity, deceleration and orbit of 35 double station meteors were measured. The magnitude distribution index was high, as a result of which there was no excess of meteors near the horizon. The light curve proved to be extremely flat on average, which was unexpected. Observations of spectra allowed us to derive the compositional information of the Draconids meteoroids and showed an early release of sodium, usually interpreted as resulting from fragile meteoroids. Lessons learned from this experience are derived for future airborne meteor shower observation campaigns.

The computation used for the prediction of the 2011 Draconids were performed on a supercomputer located at CINES (France). The Safire aircraft was funded by CSAA, PNP, the city of Paris as well as IMCCE. The DLR Falcon flight was supported by EUFAR (FP7 EC funded project). JV is thankful to M. Wisniewski for the suggestion to fly the aircraft in tandem configuration. Data analysis at ESTEC and the provision of cameras has been supported by the ESA/RSSD research faculty. PK work was funded by the Grant Agency of the Czech Republic Grant No. 14-25251S. A collaboration between the Czech Republic and France was funded under the project 7AMB13FR006. JT was supported by grant APVV-0517-12 MG was supported by the Emil Aaltonen Foundation postdoc grant and the Academy of Finland Project No. 260027. The NASA Ames Exploration Academy supported the work by Jon Reijneveld and Peter Jenniskens. The workshops at Paris observatory were supported by CLAS.
