Passengers on a Paris-bound Qantas Airways flight spent more than 15 hours in the air, eventually ending up back in Australia, where they had started, after an Iranian missile attack shut down parts of Middle Eastern airspace.

The Boeing Co. 787 aircraft departed Perth for its usual 17-hour journey to Paris at 7.35pm local time on Monday. It reached the southwestern boundary of India’s airspace when the airline was informed of the missile attack, forcing it to turn back. The aircraft landed safely in the Western Australian capital around 11 a.m. Tuesday.

Another Qantas flight from Perth bound for London’s Heathrow Airport was also affected and diverted to Singapore, according to a Qantas statement.
