Flight 706 in knife edge? The eyewitness claims he saw a wing fall out of the clouds, then seconds later, a fuselage with wing attached?
A five degree glide slope is survivable. And impossible with the reported roll angle. At a ground speed of close to 200 mph (I find that hard to believe), we are talking pure fantasy.
If 90 degrees roll angle and Stalled, she has also already spun, and wants to get on her back. That is completely incompatible with the debris trail. IMO.
Cartwheel? Certainly possible, but I am missing some important evidence.
