According to the FDR, the rudder pedals moved from 1.7 inches right to 1.7 inches left, 1.7 inches right, 2.0 inches right, 2.4 inches left, and 1.3 inches right between 0915:52 and 0915:58.5. Also, the FDR showed that the control wheel moved 64º to the right at 0915:51.5, 78º (full) to the left at 0915:53.5, 64º to the right at 0915:55.5, and 78º to the left at 0915:56.5.
The airplane performance study estimated that, at 0915:53.2, the rudder was deflected 11º to the left, and the sideslip angle at the airplane's center of gravity (cg) was about 4º to the left (after peaking temporarily at 5º to the left).21 At 0915:56.8, the rudder was deflected 10.2º to the left, and the sideslip angle was about 7º to the left. At 0915:58.4 (the time that the right rear main attachment fitting fractured), the rudder was deflected between 10º and 11º to the right, the sideslip angle was between 11º and 12º to the right, and the airplane experienced a 0.2 G shift to the right in lateral load factor.
This is not new stuff..... many years ago a B-52 lost its vertical stab on a low level in turbulence (they landed the acft with no fin). They shortened the hight of the stab which reduced the bending moment at the attach point. In spite of the mod my B-52 instructor pounded into me how not to handle the controls in turb, MITO, wakes, stalls, lazy 8s, etc. We did this training in the jet not in the sim. I have not received this type of training while at the airlines "in the jet". The closest thing we do is "upset training" "in the sim". Just isn't the same.

This film includes some absolutely amazing footage of an actual B-52 which has lost its vertical stabilizer! The film serves as a briefing on what to do in this unusual situation. This a really interesting short film!
