34:41 it shows the tail fin camera lens being cleaned prior to installation on the first prototype. So far so ordinary. However, I couldn't help but notice that there's a laser safety warning sticker on the electronics assembly behind the camera window.
I'm no optics expert, but last time I looked cameras didn't need a laser. So what is it for? Was it for the prototypes only? Fog / precipitation / weather detection? Wind shear detection?
Or are all A380s laser scanning the topography everywhere they fly to supplement airline revenue by selling live-ish geographical data? Airbus getting ambitious with their world domination plans, using their aircraft (fly by wire = remote controllable!) as an airborne laser menace?
