At very close range like that, the missile is essentially ballistic
since it is most likely incapable of the high-g maneuver that would be
required to correct for aiming error. The fighters would not be able to
react in that time frame- they could sweep the immediate ground area
prior to takeoff and clear it of any suspicious intruders- and/or make
them very nervous about a quick annihilation once spotted- this will
make their aim worse-)
