If Superman (or whoever) uses the remaining distance between you and the ground to reduce the impulse on your body. But they also have to be careful about their speed coming in to grab you, because they could easily substitute your impact with the ground for an impact with them.
Eh, Spiderman is both insanely fast and strong compared to a normal person, still. He can canonically catch cars and punch concrete and the like. Not sure how much spidey sense plays a role, but he's nigh impossible to shoot, too. He'd likely be capable of the feat just with his strength and speed, let alone his other options.
Superman is still waaaay stronger and faster but he's pretty much cheating even for a super hero. lol
I think their thought was if Spider-Man came swinging in for the catch, at that point it’s basically out of his control how hard he hits. But he could potentially save the person via other spidey means
Ahhh yea, the cliche swing and nab IS a pretty tough one. Not sure he'd be accelerating anyone slowly enough mid-air! At least Superman can just kinda' will himself what ever direction, or how ever his flying works.
See, that's how you know people here have never touched grass. Otherwise they'd know how big of a difference it makes to fall on grass vs concrete. All over a few mm of yield.
Also anecdotally I've seen videos of people catching falling children (back in the day in/r/DadReflexes). It works, empirically.
