One day on CDG Ground frequency a pilot of A380 calling:
a/c: Ground, ZZZZ 333 Super, request push and start.
atc: ZZZZ 333, push and start approved.
A few minutes later:
a/c: ZZZZ 333 Super, ready for taxi.
So atc passed taxi clearance.
After two or three minutes:
a/c: Ground, ZZZZ 333, due to technical problem we need to return to the gate...
It took them about ten minutes to declare "ready for push" again, but anyway as long as I was on the frequency they didn't use "Super" in the callsign...
