== Technical Adviser (Under Accuracy) == 

 Harry Lange should be listed as a technical adviser because he was at Marshall Space Flight center with Fred Ordway. 
 And hired by Kubrick ... Ordway and Lange as a pair. 
 Yes he did production design but , even if Ordway was the lead, Lange was also and engineer as well as a crack technical illustrator, and did some technical advising too.
