Very few people will know what I'm talking about, unless you're from the former Soviet Union. There was a film made back in the late '70s or early '80s about a group of people taking off in a Tupolev TU
-154 during a volcanic eruption. The take-off scene actually shows two different aircraft taking off at different times - the first one crashes, but the TU
-154 makes it, barely, after rolling over a large crack in the runway which damages the rear fuselage. The catch in the take-off scenes - the planes used aren't even real, and you can see the toy wheels underneath them. Remember those toy PanAm 747, Continental DC-10s, etc. with wind-up wheels in boxes under them? Well, that's what was used in this film!
To make matters worse, while the TU
-154 is airborne, the damage in the rear fuselage propagates into a crack which the crew tries to repair - by climbing through a hole in the ceiling of the rear cabin INTO THE CENTRE ENGINE DUCT AND OUT ONTO THE FUSELAGE THROUGH THE INTAKE to try to repair the crack with a blowtorch!!! Totally unrealistic. One of the crew members ends up severly frost-bitten and in danger of dying from his out-of-aircraft experience.
As the plane is descending, the rear fuselage begins to separate, and when it finally lands, the entire tail falls off onto the runway, bursting into flames. However, no one on the aircraft is killed, so it's a happy ending. But seriously, it's the worst aviation movie I've EVER seen.
