(anon analysis from latest video I saw)
Upon review of additional video of (Endeavor Air/Delta) crash in Toronto it appears the rate of descent, angle of attack and air speed were too "hot".
Video is blurry & too far away.
Couldn't see clearly the flaps, slats, speed brakes = ie. wing flight control surfaces configuration
Looked like plane rolled slightly STBD at the last minute before ground impact and had a hard landing w/ right main gear impacting ground 1st.
Possible RT gear collapse.
Then RT wing dragging the snowy ground = shearing off.
LT wing maintaining lift.
Causing plane to (Roll STBD) & (Yaw STBD - from RT wing drag) then fuselage roll/slide down the icy/snowy runway.
