Owners and pilots of two Daher TBM turboprops recently completed milestone, 2,700-nm flights over the South Pole, marking the first legs in earning the Polar Diamond Circumnavigator Diploma bestowed by the Federation Aeronautique Internationale.

The recognition has been awarded only once. One of the pilots, Sebastian Diaz from Santiago, Chile, flew his TBM 850 with his father, 88-year-old Patricio, a licensed pilot, and his son Sebastian Jr., who were copilots.

The other TBM owner, Dierk Reuter from Chicago, flew with his son Alex on his TBM 930.

The two aircraft left Jan. 1 from Punta Arenas in Chile and overnighted at Teniente Rodolfo Marsh Martin Airport on King George Island, before reaching the South Pole the following day and making the return journey.
