Side note, The deflection angle to stop a "flying kick" is upwards.
If the leg is deflected upward the momentum of the body will cause the kicker to rotate so their back and tailbone are parallel to the ground and then the person can be slammed down.
A fly kick is generally a Run Jump Kick which requires a lot of space and there is a huge commitment to the technique.
For experienced people it is very easy to avoid this kick and counter while the person is still in the air or as they touch down.
If they side step they have access to the persons back and a good tackle or side kick can take their balance and cause some real trouble for the kicker.
It doesn't mean it wouldn't work on occasion but it would be a very low probability shot for someone who has experience kicking.
