KeysCapt,
I was told it was a towing accident. If you have a source for it being any different, let us know.
There are numerous references to this happening during taxi and not under tow. Here is one:
A380 Wing Clips Building While Taxiing at Le Bourget | Flying Magazine | The World
Here a quote:
In the case of the A380, the aircraft's right-hand wing-top hit a structure during taxiing at Le Bourget. The incident occurred around 3:50 p.m. local time at the Victor taxiway.
Aviation Week
Just Google "A380 Paris incident" or similar and you will see pages of them.
EDIT: I've found other references that say the aircraft WAS under tow at the time, so I guess there is sufficient confusion to put this in some doubt.
