Bruising concurring silently, I can attest one should take great care not to combine flying with biking.
Funny thing was I thought I was safe, because I had made it all the way down the hill. Not seeing much due to snow, and the tires drifting , slipping and skating all over the place.
Then, in an underpass, someone thought it would be brilliant to alternate between heated areas and just plain nothing.
The light powdery snow caught the spokes, which means its largely slicks and no grip, with varying degrees of ice the result was already a darwin-award in the making.
I was able to make the correction for the turn, but I couldn't roll in air. Came down with jazz-hands into a push-up.
One always finds the time to address the situation in retrospect, its like everything slows down to tell you how you could have fared.
