Without a doubt it is a posed picture,the model insurance used to publish similar but genuine shots of cars that had model impact damage,the model shown in the picture would not have the inertia to do the damage shown,something much heavier has hit the windscreen.
A powered IC model aeroplane has been known to cut through a caravan roof,it happened around here a few years ago.
Also I once had a Wayfarer biplane that lost radio contact and flew away in the early unreliable reed days,a big model,it flew into the side of a house breaking the brickwork,now that does take some doing !
Some of the worst accidents that I have seen involved helicopters,the sight of one of these thrashing itself to destruction on the ground has to be seen to be believed,you just move very quickly !
