there is a lot more to this
1. the aircraft was delayed 5hrs at JFK, somewhere it was realised that they were not going to make it to Paris without crew running out of hours.
2. the flight at some time was diverted to MAN to offload crew and bring a new crew from CDG on one of the scheduled flights.
3. Crew arrived at MAN and then found that the a380 had gone tech
4. 2 A320 and an A318 were flow from Paris to collect passenger to continue onwards to Paris
5 A380 will spend night at MAN and hopefully depart tomorrow
