D-ABTE is used as a testbed for the Connexion by Boeing internet service, mostly used on FRA-IAD now and wears "first real internet on board" sticker on the rear fuselage. Took photos in the hangar today, probably not a.net material but maybe for the justplanes.com site.
Also, the second 332 (D-AIMD) has arrived, I will try to upload photos of both next to each other. They will enter service this week. (don't ask me for details yet, will have to check).
