The inspiration for the General Harding character, Roswell, and Area 51 were topics discussed at the SDCC Project Blue Book Panel.
At San Diego Comic-Con 2019, Project Blue Book held a panel to tease information about the second season of the series. The panel included Aidan Gillen (Dr. J. Allen Hyenk), Michael Malarkey (Captain Quinn), Laura Mennell (Mimi Hynek), Neal McDonough (General James Harding, David O’Leary (Creator/Executive Producer/Writer) and Sean Jablonski (Showrunner/Executive Producer/Writer).
Starting off the discussion were O’Leary and Jablonski who say they are looking to have more fun in the second season. This comment likely translates to exploring more fictional storylines. The duo explained they do try to make the show fact and science-based, but feels it also has to be fun.
