Having done both sky diving and paragliding... yes, this impresses a lot. Although I admit I have no clue how easy or hard it is to "fly" using one of those wing suits.
I've always wondered how much they are able to angle up and convert speed into altitude. Their glide slope seems terribly steep. In the case where the guy hits the bridge, he would have cleared it if he only had 1 meter more altitude, but instead he went through the railing like it was a cheese grater at some ridiculous speed. It appeared he wasn't able to 'pull up' the slightest bit, even though he was moving so fast.
The fact that they can't land using the suit alone, and still need a parachute, indicates to me they are falling, not flying.
