Yes, there's two of them. 16+01 and 16+02. They used to be the German version of Air Force One, flying our president or the chancellor. In 2020, they both overflew my house a few times. You found 16+02. 16+01 is this one: https://globe.adsbexchange.com/?icao=3eb1a6 They were replaced by one or two Airbus A350s. I was rooting for getting a A380s, just to tease Mr. Trump a bit, but unfortunately, that didn't happen... ;-)
