The plane that maneuvered up, no pax injuries. The plane that was ordered to descend had 100 injuries. I can only assume that the pax in the DC10 which was ordered to climg, the pax simply felt g force, pushing them into their seat. The 747 on the other hand I can only assume from how these people sustained their injuries. Those were out of their seat or not wearing a seat belt who went zooming to the ceiling or thrown backwards 10 rows or whatever it was. I can only assume that the pilot pushed down on the yoke in a manner which he created negative g's. But what about when we here about injuries due to extreme turbulence the pilots were not aware of?
I can say that one time I was in severe or extreme turbulence. Now we were lucky in that the severe turbulence coming into Pittsburg. Was known about several minutes in advance. So, the FA's were able to quickly secure the cabin, no drinks or food out, carts put away. To the FA's I'm sure I'm missing things but I think I got my point being we were well prepared for this. Now, especially for those of you who've flown hundreds of times, or pilots who get that number into the thousands, career FA's who also probably fly more than a thousand times. And I think I'm being conservative if anything. I'm not saying I've been through worse turbulence than you have, Just that what I went through can be considered severe.
I often felt weightless and on several times felt some impressive g forces pushing me into my seat
I've seen several hurricane hunter shows. Hard to think that you're going to find worse turbulence than that, and while obviously the pilots and any others who were in the plane were secured as well. Still, it often appears to me that they experience more of the weightless zero g with down drafts, or is it possible (pilot and FA or those who've flown several hundred times input please) can turbulence create such a down draft that creates negative g's?
I've often wondered if "some" of the injuries sustained by turbulence if not faked, greatly exaggerated for lawsuits or some sort of money making scheme. Obviously with the unexpected turbulence with the seat belt sign off people in the lav or in the isles, FA's up and about the cabin and gallery. For those not wearing seatbelts are thrown up and out of their seats or straight up causing significant damage to the ceiling. Can turbulence really cause negative g's to create and or sustain such injuries?

A hurricane is primarily horizontal windshear and while that creates quote some turbulence, it's mostly in a horizontal plane, i.e. left/right.
Other turbulence, caused bij jetstreams, mountains, buildings or other aircraft is more verticale, creating zero/negative and positive g loads.
And yes, it is possible to lift a fully loaded trolley several meters into the air during such an event, if you are unlucky, so a human body wouldn't be any different.
