After receiving De Siebert's authorization, the slipway was lengthened on January 24, and then again on 28. Operations were carried on among problems and obstacles until February 6, when Caproni was informed that 30 wing ribs had broken and needed to be repaired before the beginning of test flights. He was infuriated, and kept his employees awake through the night to allow the tests to begin on February 7.
Following De Siebert's authorization, the slipway was lengthened twice: first on January 24 and then again on January 28. Despite encountering issues, work continued until February 6 when Caproni discovered that 30 wing ribs had broken and needed repair before test flights could begin. Furious, he instructed his employees to stay awake all night so tests could commence on February 7.
