US Air Force flight to Antarctica turns back after Russian hazardous space activity warning

Key Points:

• A U.S. Air Force flight enroute to Antarctica from Christchurch, New Zealand, turned back after being notified of "potentially hazardous" space activity, specifically a planned missile launch, by Russian air traffic authorities.
• New Zealand’s Civil Aviation Authority issued a Notice to Airmen (NOTAM) to alert aircraft operators of the potential hazard within New Zealand’s Oceanic Flight Information Region, which covers a vast area of international waters.
• The flight, a routine resupply mission typically conducted during the annual Winter Fly-in (WinFly) period, was part of ongoing operations supporting Antarctic research programs, including the U.S. Antarctic Program and Operation Deep Freeze.
• The C-17A Globemaster III took off from Christchurch but landed back approximately two and a half hours later, with the decision to turn around made based on the NOTAM and safety considerations.
• Christchurch serves as a key logistics hub for both the U.S. Air Force and New Zealand Defense Force in supporting scientific missions to Antarctica, including transporting personnel and cargo ahead of the research season.
