Objects falling through the atmosphere have a terminal velocity determined by their weight and aerodynamic qualities. When the weight of the object and the aerodynamic drag balance out, the object is at its terminal velocity.

bljones I believe the terminal velocity of any object is 0. However, just before that, I think it is 10 m/second squared

135 mph would be my guess, since people are about 120 mph and it's based on surface area to volume ratio IIRC (similar density). Air resistance goes up dramatically with only slight increases in speed, hence the smallish, 15 mph increase, even though the cow is much heavier.

It the moment after impact? Burning fiberglass, Dacron and diesel, mixed-in with holding tank contents.

Then and there'd be a lot of steam everywhere.

I guess that qualifies as stinky.
