As far as I know aircraft was for quite a time already soaked in water, moving it itīs not the best option knowing that many taxiways drainage covers had already been washed away by the force of water.
Looks like aircraft was flown a couple of hours later to maintenance center in UK. Bombardier stays that a pre-inspection is needed before any flight take place.
Other pilots and aircrafts where in place, no one moved them.
I wonder if they used taxi lights.....
