EC-NXD, an A350-900 (NEXT cabin variant), has been reportedly involved in a minor collision at GYE (Guayaquil, Ecuador) today while taxiing to leave for MAD.
It was receiving a water cannon salute and there's video of the incident in which the left wing makes contact with one of the fire engines. The plane returned to the gate and is now more than four hours delayed leaving GYE.
Hopefully it's not put out of service too long and they'll be on their way shortly.
