35 metres through the air, what speed must this fella be going at ? And when you see the news clip you can see that there is snow on the ground.
Depends on the angle of the embankment and where in the "flight" he hit the roof, plus the height of the top of the embankment w.r.t. the church.
Assuming an embankment slope of 30 degrees and that he hit the roof, 35m from the embankment, at the top of the arc, then he would have needed to be doing about 60mph.
