There is no indication that SG:A is the city-ship being referenced. Atlantis does not fly by Orion-drive and is in no way the first Sci-fi reference to City ships. They go back at least as far as "Cities in Flight" by James Blish and possibly further, although I've found no evidence of this. -- (talk) 12:04, 19 January 2013‎ (UTC) (please sign your comments with ~~~~)

Also note that this comic is no. 786, which is the amount of known exoplanets. -- ‎ (talk) 09:17, 21 February 2013‎ (UTC) (please sign your comments with ~~~~)

But this was released 2 years earlier than that count; still it's interesting factiod... Mark Hurd (talk) 11:07, 13 April 2013 (UTC)

Footfall by Larry Niven is the best example of city-ships in line with Project Orion. Basically the bigger they are the better. Big metal plate with a city on top and nuclear bombs exploding underneath. And the project started in the 50s. [1]-- 04:53, 11 May 2014 (UTC)

Before restarting Orion, why not start with a more modest goal: a facility to assemble spacecraft on the moon from parts made on Earth? Even without the mining, it'll mean we can launch a craft from Earth in several smaller rockets instead of one big one. Promethean (talk) 01:30, 14 February 2018 (UTC)
