Speed was not an issue, and usually never is, unlike some people would like you to think.
I'd say it is when a collison actually occurs... lady luck was operative here, anything could have happened with that sort of momentum at work.
In fact, if that video really is anywhere near true speed, then:
a) there's almost certainly hidden inertial damage to the CRJ airframe
b) there's almost certainly a few on board with pulled muscles in neck or back, at the least
That was a good few degrees/second... oldies onboard could have suffered, and a strike elsewhere could have produced a fire.
Not something to minimise, quite enough danger when airborne
