The visual indication of missile path seems very straight compared to those in real videos ~ there seems to be a lot of oscillation around the mean flight-path.

Don't know whether this is because missile flight and guidance are in an early phase or because this 'wobble' is under-represented generally. It is only slight when seen as a 3d line, but when viewed from the 'end' like this, the error correction responses should be more visible IMO.
