In "The Final Test" mission, disguise yourself as a mechanic. Next, sabotage the ejector seat of the fighter jet (requires a wrench which you can be found near the jet). Read the "Exit Strategy" paper (by the fighter jet). Then, speak to the target and let him follow you to the jet. Finally, interact with the exit strategy paper again and give him instructions how to use the ejector seat. He will then fly away on the seat and you can safely exit the area.
