Hi Umberto,
Nice addition, the GPU. Excuse me, but I take this momentum to ask you something. When the lavatory truck will be introduced, is it possible that at the same time a van stops at the back stair, and 2 cleaning crew step out, climb the stair with cleaning equipment (bucket, mop or trash bags) and clean the aircraft for x-minutes? That would be an awesome addition.
