266 extractive question-and-answer pairs built from OpenFlights: Airport and airline data, published by openflights.org. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. 202 of the 266 pairs (75.9%) are explanatory questions and 64 restate a figure. 99.25% of rows pass the corpus quality gate.
