"An exhibition under the motto "Technology between phantasy and reality" , launched by the Vereins-
und Westbank allowed a look into the future. Considering the oil crisis, there are doubts, that the idea
to keep large aircarft in the air all the time to allow TV-broadcasts and make big TV-antenna masts
redundant will ever be realised. Interesting is the shape of the "TV-aircraft": It reminds to a glider and
the turboprop engines with contra-props actually could replace jet engines one day"
So, it was more a "what-could-be-in-the-future", than a project, although the sketch looks quite professional.
But using such a big, manned aircraft as a relay seems quite strange to me, too.
