Airships cannot be sent into orbit.
I didn't say that I think sending an airship into orbit is possible; I even said I think their project is a bit crazy. You either have reading comprehension problems, or you like responding to issues people haven't raised. Personally I seriously doubt airships can be sent to orbit, but not because I believe the Earth is flat

No lighter than air aircraft has went higher than 53km, and that was merely a 40kg balloon. The record altitude for a dirigible is less than 12km. I doubt a dirigible could ever reach an altitude much higher than the current record for lighter than air aircraft. And like Jason_85 indicated, it would essentially have to be made only of hydrogen to do it.
However the people behind the project do certainly think that sending an airship to orbit is possible. So what I said is that if the project
somehow works and they do send an airship to high orbit, it would mean they would become part of the Conspiracy. Nothing more, nothing less.
It needs to be that huge because it's driven by huge propellers. I did not suggest propellers an an acceleration mechanism.
Either you haven't even looked at the link I posted, or it's a further indication that you have poor reading comprehension skills. It only mentions propellers in the case of the first part of the project, which is supposed to be an atmospheric airship. The orbital airship that I was referring to, the one which is supposed to be
6000 feet long, is stated to have "electric propulsion"; the pdf document then goes on to mention a flight test for an
ion engine intended for that same orbital airship.
