The I.F.T. assistant was an unnamed employee of Emmett Brown's Institute of Future Technology in 1991. She welcomed the time travel volunteers — i.e. park guests — to the Institute via video screens and made various other announcements during the course of the visit, as well as introducing the safety tips for traveling in the 8-passenger DeLorean (which were demonstrated via a short film by actors dressed as crash test dummies, and narrated by a male announcer's voice) and telling the volunteers to enjoy their flight across the space-time continuum.
