Tanner was complicit with the Jacobs administration for rushing the development of a hybrid fighter that killed Steven Hiller in the 2007 ESD Spring Expo. Prior to the incident, ESD scientist David Levinson warned Tanner about his concerns about the hybrid in which Tanner disregarded his warnings and had him removed from the hybrid project. Much to Tanner's reluctance, Levinson was appointed as the new ESD Director.
