Occurred on June 13, 2019 / Brisbane, Queensland, Australia

Info from Licensor: "Qatar Airways Boeing 777-2DZ(LR) Reg. A7-BBG as flight QR921 displayed some truly amazing and very beautiful rainbow contrails as she transits over Brisbane. This has to be one of the most spectacular rainbow contrails I have yet seen with a B777. The seeing conditions were just about perfect on the day, being in Winter with slightly cooler conditions and little air disturbance looking directly upwards to 9.3 km. The aircraft was en route from Auckland, New Zealand to Doha, Qatar at a height of 30,492 ft, Speed 793 km/h, Track 300°."
