That must've knocked the wind out of him. A couple minutes he should be fine.
This one made me feel all sorts of ways. Most of all I wish he had not seen it coming at the end. That last second of life would be a terrifying way to end things. I guess you can't really tell... but it looks like he may have been messing with a face mask? The white thing in his hands that flew last second... if so, that's all the more sad in his last moments he was trying to protect others and in doing so failed to protect himself. So sad. I tried to look this up and despite there being a date I'm unable to find any background information. I mean I obviously know how it ends. But I'd be interested in knowing more about the victim. If anyone else may know anything... maybe where even?... it would be greatly appreciated.
