About to go to a hiring event for an aerospace company (no experience in aerospace) any tips?

Hi all. Just as the subject says, I was messaged by a recruiter to apply for this hiring event with a possibliity for an interview the following day. The hiring manager then selected me based off my resume. The thing is, its for an aerospace company and they use military standards to write their manuals. No experience wriitng for aerospace or any military branch. How can I prepare for this event?
