[Help] Trying to find an old movie title

I am trying to find a movie from which I have a single scene stuck in my head since I was about 7, seen on tv back in Italy in the mid 80's.

What I recall is (what I think was) the closing scene of a male actor looking up in the sky to a plane flying. The planes explodes and the man, not surprised, lights up his cigarettes and moves away from the shot.

I've heard my mother saying something along the lines of that being a famous movie. I asked explanation of the weird scene and I think she said "the man's thoughts became reality" or sort. As for the male actor, for some reason I think of a young Alain Delon, although could have been an Italian actor.

It's been years I have this few seconds stuck in my memory and I think I owe it to watch the full movie once.
