What the @Arianespace Ariane 5 would have looked like in its @esa Hermes configuration. I would have loved to have seen this thing fly. Credit: ESA 
For context, Hermes was an ambitious crewed spaceflight program created by @CNES in 1985 and later adopted by ESA. The program was canceled in 1992 because of its projected cost and some geopolitical developments with Russia that enabled ESA to utilize Soyuz.
Although no Hermes spacecraft were ever built, a mockup was created for the Paris Air Show. According to @ESA_History, it was then used to demonstrate the European Space Research and Technology Centre's (ESTEC) capacity to accommodate large-scale spacecraft.
The mockup then became a feature of ESTEC's Space Expo visitor centre that opened in 1990. I'm not sure if it is still there. Any info on where the Hermes mockup is now @ESA_History?
