the airbus a380 was delayed in october 2006 due to the use of incompatible software used to design the aircraft. primarily, the toulouse assembly plant used the latest version 5 of catia (made by dassault), while the design centre at the hamburg factory were using the older and incompatible version 4. the result was that the 530 km of cables wiring throughout the aircraft had to be completely redesigned. although no orders had been cancelled, airbus still had to pay millions in late-delivery penalties.
