wsherif1 you overlook several fundamental points of flight mechanics. First ‘g’ is an acceleration; to generate force you have to specify which mass is being accelerated (F=ma). Was this mass the air or the rudder? If it was the rudder then who moved it?
Second, if it was an external force (air mass) it would have been applied reasonably equal to all of the aircraft or at least the rear end. A vortex may have been local to the fin and rudder in combination but not just one or the other in separate instances. Furthermore, with a nose high / turning climb the forward fuselage should also be under the effect of the vortex, thus the whole aircraft is deemed to move. Or are you suggesting that the earth moved instead?
