thanks for answer Drondong!

I agree with you;

but what about the "bad black smoke" seen in air by wingman and...no more visible one minute later, by witness on ground, just some seconds before the crash???

Does it mean that there would have been no more oil to burn?

Problem for me is to understand WHY the plane was at first smoking badfly and one minute later...no more, but with still runing (loosing altitude) motor.

Any idea?
