During the final take-off roll, the Aeroflot Tupolev Tu-154 passes in front of the same burning wreckage and fire trucks twice.
The Aeroflot Tupolev Tu-154 aircraft appearing throughout the second part of the movie is registered "CCCP-85131", which is also its radio call sign. Immediately after its final lift-off, its registration changes to "CCCP-85179" (as a different scale model was used).
One of the flight crew members successfully climbs in and out of the S-duct of the flying trijet to reattach the tail to the fuselage.
