TLDR
In this paper, a European airborne meteor observation campaign was organized, supported by ground-based observations, and two aircraft were deployed from Kiruna, Sweden, carrying six scientists, 19 cameras and eight crew members.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.read more

New methodology to determine the terminal height of a fireball
TL;DR: In this article, a new approach was developed to forecast the degree of deepening of meteoroids in the Earth's atmosphere by using the fireball terminal heights observed by the Meteorite Observation and Recovery Project operated in Canada between 1970 and 1985.

The Ensemble Properties of Comets: Results from Narrowband Photometry of 85 Comets, 1976-1992
TL;DR: In this paper, the authors present the results of narrowband photometry of 85 comets observed over a period of 17 years, showing that there is no differentiation with depth in the cometary nucleus, that most comets are very similar to each other in chemical composition, and that the dust-to-gas ratio does not vary with the dynamical age of the comet.

TL;DR: The bulk of the comet 81P/Wild 2 samples returned to Earth by the Stardust spacecraft appear to be weakly constructed mixtures of nanometer-scale grains, with occasional much larger ferromagnesian silicates, Fe-Ni sulfides,Fe-Ni metal, and accessory phases.

TL;DR: In this paper, an analysis of the Prairie Network fireball trajectory data was performed to distinguish between chondritic meteorites and more fragile early-type carbonaceous chondrites, and it was concluded that if the carbonaceous material occurs in reasonable abundance among the fireballs, it has been properly identified by this analysis.
