Found an interesting quote about a B52 which I didn't want to disappear in time so I thought that I would post it here,
"This also reminds me of the issue with the B-52G. When going around and applying maximum thrust, fuel moved in the tanks displacing the CG aft of the aerodynamic center, making the aircraft statically unstable. Two B-52s and crews were lost. The solution adopted was a simple detent in the throttle quadrant which discouraged rapid thrust build-ups."
