prompter: Items 5 and 11 seem to refer to same event. Did Juan de la Cierva make his first autogiro flight on January 9th or January 27th?

assistant: Juan de la Cierva made his first autogiro flight on January 9th, 1923. However, there is a discrepancy between sources regarding the date of the first documented flight of an autogyro. According to Alejandro Gomez Spencer, the first documented flight was on January 17th, 1923 at Cuatro Vientos airfield in Madrid. However, Juan de la Cierva claimed that he flew an autogiro on January 9th, 1923 at Cuatro Vientos Airport in Madrid.

prompter: This is even more confusing! Now we have three dates, the 9th, 17th and 29th. Could you try to find sources about these different dates? Are there maybe scans or text dumps of newspaper articles available? Let's try to solve this mystery together!
