Don’t forget one detail: actually, the media are concentrating on the Pope’s funeral, and the french Media will most probably also focus on the prince Rainier of Monaco till the 15th April.
The first flight of the A-380, which would undoubtely be a big media show, would then go nearly unnoticed on TV news… So that might be another reason to wait a bit, even if the plane is ready..
I doubt it.
The delays were announced weeks before either of them died. Coincidence thats all
