I´ve got a problem, in the start of the mission i see about 0,3 sec of the cockpit and the world normally, but then the plane explodes and the planes are not in the runway in the start, they are about 100m back from the airfield.

Hmmm. What airfield and which plane?
Some of the airfields are not for big bombers. Try to select other airfield or reduce plane density.... If the planes are too far from the AF, there might be a forest textures and that means Ka-BOOOM!
I will look at map and edit map_t, if necessary.
TY for info!
