Light fury catching Hiccup failed physics

So i talked a lot about the scene where light fury catches hiccup mid air, and i was explaining that hiccup couldn't survive such a change in speed. So today i calculated the force he experienced and i have a conclusion. Sooo according to physics this scene is impossible, because according to my calculations he experienced the force of 10g's(700kg) at this force he should have lost consciousness and have a couple broken bones(because it was a shock rather than continuous force, he was experiencing this force for around half a second, human can withstand around 15 seconds of 10g's). So basically at the moment of stop he felt 700kg pulling him down, and this is very dangerous, but not really deadly.

Im attaching calculations for those who like deep explanation in the comments.

70kg=Hiccups approximate weight I was rounding most of calculations so i don't get a million decimals, it doesn't really matter because end result wouldn't change by alot.

How this scene could be more realistic? If light fury made a proper trajectory with proper force distribution and smooth stop insted of what we have. I also used "speeding" instead of "accelerating" in calculations

Again pls appreciate it i was making this at 5am because i didn't want to sleep XD
