The PILOT instrument took off on the morning of the 24th of September from Timmins airport (Ontario, Canada). This third flight of this instrument, on board of a stratospheric balloon, lasted for 25 hours, among which three hours to rise to the ceiling altitude, one hour dedicated to the instrument tuning, and 20 hours of scientific observations at the ceiling (about 38km on daytime and 34km during night). All flight systems and the scientific instrument behaved nominally, and the data produced by the instrument are of very good quality.
