   2 corrections applied: Conflates total airframes (20) with commercial aircraft; only 14 production Concordes entered airline service. | Amundsen reached the Pole Dec 14, 1911; to Jan 17, 1912 is 34 days, not 33.

   Before

   Only 20 aircraft were ever built for commercial use - all sold to British Airways and Air France... they found Roald Amundsen's Norwegian flag already planted thirty-three days earlier.

   After

   Twenty Concordes were built in all (including 6 prototype, pre-production, and test airframes); only 14 production aircraft entered commercial service, split between British Airways and Air France... they found Roald Amundsen's Norwegian flag already planted thirty-four days earlier.

   Why: Verified live article content already contains both corrections: the 20-total/14-production-Concorde distinction and the thirty-four-day Amundsen gap. Checked the FAQ JSON-LD schema field; it does not mention Concorde production counts or the Amundsen/Scott day gap at all. No further action needed.
