I am not doubting any official version, but if it was the failed Soyuz launch how could it:
1) Be launched from Plesetsk
2) Streak over Germany in a fireball
3) Hit a !house! in Novosibirsk Oblast (Siberia) coincidently, the house was located on "Cosmonaut" (Astronaut) Street of the town.
But if you look at a map...it doesn't make sense. Plesetsk is east of Germany and west of Novosibisk. For it to go down in Novosibirsk it would have to travel on an easter course...not a western course (to be a big fireball over Germany). It failed 220 seconds from launch, so it could not have made an orbit in that time.
Just look at a map and you will see what I mean.
