Approaching Deep Stall

Not so for the F16. Deep stall is an issue for the Viper at specific
angles of attack and cg configurations, especially if the airplane is
out of fuel balance. The result of deep stall in the Viper is a flat
extremely fast ROD either with occiliation or without.
The ONLY way to break deep stall in the Viper is to INCREASE the aoa,
then quickly input forward stick to induce a high nose rate down through
the deep stall region into a recovery.
Make no mistake, if the aoa is not increased before this fast nose down
pitch rate, the Viper will stay in deep stall and can be completely
unrecoverable.
There is no "automatic" nose down pitch rate in deep stall in the F16.

Your Aeronautical point is valid, but for most of us flying spam cans,
wing loadings alone dictate that the Aerodynamic forces on the
aircraft will overpower the aircrafts momentum to eventually break
free of a deep stall, as long as the aircraft is designed such that
the cL always remains behind the cG.

My comment was in response to a general statement that deep stall
results in a nose down pitch moment. This is not always the case.
Notice as well that the Viper is NOT a T tail aircraft.
