A fifth and final test flight of the NS2 propulsion module was conducted on 5 October 2016.[33] The principal objective was to boost the passenger module to the point of highest dynamic pressure at transonic velocity and conduct a flight test of the in-flight abort system. Due to subsequent buffet and forces that impact the propulsion module after the high-velocity separation of the passenger capsule that are outside the design region of the PM, NS2 was not expected to survive and land, and if it did, Blue had stated that NS2 would be retired and become a museum item.[8] In the event, the flight test was successful.
