Passengers on Qantas flights between Sydney and Johannesburg have encountered unexpected delays recently, with the airline attributing the disruptions to falling rocket debris from Elon Musk’s SpaceX.
The southern Indian Ocean, a region frequently crossed by Qantas flights, has become a designated splashdown zone for re-entering SpaceX rockets.
Qantas explained that it often receives late notifications about rocket re-entries, forcing the airline to delay flights to ensure passenger safety.
“Over the past few weeks, we’ve had to delay several flights due to advice from the US Government regarding SpaceX rocket re-entries,” the airline told Euronews Travel.
Flight tracking data and SpaceX launch schedules suggest a clear link between delayed Qantas flights and recent Falcon 9 rocket launches.
For instance, a January 10 flight from Johannesburg to Sydney departed five and a half hours late, coinciding with the launch of a Falcon 9 carrying Starlink satellites.
SpaceX’s Falcon 9 rockets are partially reusable, with the first stage returning to Earth for future launches.
However, the upper stage, an aluminium section weighing 3.5 tonnes, remains in orbit before eventually burning up on re-entry. Occasionally, pieces of debris survive the descent, landing in remote areas or, in rare cases, private properties.
Dr James Pearson, a flight route analyst, noted that Qantas’s Sydney-Johannesburg flights are particularly affected by their southern route over the Indian Ocean.
South African Airways flights between Johannesburg and Perth, which take a more northerly path, are not impacted.
While the risk of space debris striking a commercial aircraft is minimal, airlines prioritise safety. Qantas has been in discussions with SpaceX to refine the timing and location of rocket re-entries to minimize disruption.
“Customers generally understand this is outside of airlines’ control,” said a Qantas spokesperson.
The Aerospace Corporation estimates that 200–400 pieces of space debris fall to Earth annually, with numbers expected to rise as satellite deployments increase.
SpaceX alone has launched over 7,000 satellites and plans to expand to 34,000, adding to the challenges posed by dead satellites and discarded rocket components.
