Airbus has Guppys in collections both at Hamburg and Toulouse.

In fighter cockpits they had the famous “relief tube”. A pipe next to the seat to the outside world to pee in.

In bombers they had the one mentioned above. I was reading somewhere the typical “water” used to flush it at altitude was the remaining hot coffee in big thermos carried on long flights. Lavs would ice up frequently.

Some fantastic airplane collection he had and so nicely restored and displayed in flight.
I liked how he did stuff to enjoy for the public: His music museum and the library in Seattle, the airplane collection, the cinema and program, I think a music festival as well. Somebody who shared his passions.
Hopefully Stratolaunch will fly.

They only confirm the decision to move it to Germany. An airworthy restauration is not confirmed anymore.

German wartime build quality went down over time. Expected aircraft service life was reduced to just months or weeks before being shot down or damaged beyound repair. Construction was simplified in many details, ersatz-materials (wooden parts instead of aluminum) chosen, and when damaged many airframes were just thrown away. Production lines were moved into the open and hidden in woods and forced labor staff used for assembly. As the war neared it’s end the germans had only very limited fuel supplies so what they had left didn’t fly much anymore. Finally quite a few pilots got moved to become infantry.

The BWB stamp above is the acceptance stamp of “Bundesamt für Wehrtechnik und Beschaffung – BWB” the federal military procurement office.

Later H-model US-Hueys had their exhaust blowing upwards through “horns”, while the Germans had straight out exhaust pipes towards the tail. Some chopper connaisseurs claim to hear the sound difference in flight.
