the 'aviation flight-reconfiguration' thing

there's the possibility of contributing to dynamics with respect to the
vertical axis, but only in an extremely-loosely-'coupled' way. 

unless stuff is attached to the airframe, it's pretty-much like liquid
in a bottle, and tends to destabilize because it has its own inertia
that doesn't cooperate with the airframe, and actually damps flight
control inputs.

it's why the 'fasten your seatbelts' light comes on during demanding
flight operations.
