Advanced Short Range Air-to-Air Missiles

From Tardis Wiki, the free Doctor Who reference

Advanced Short Range Air-to-Air Missiles were a type of heat-seeking missile used by UNIT.

The missiles were equipped with infrared seekers that would lock on to flying craft, and release a blaze of flame that trailed behind it. The resulting explosion was big enough to send shockwaves across a large lake.

The missiles were used to shoot the mothership of a Rintlekk escape pod over Wasdale Head, causing the bracken on the hillside to burst into flame. (PROSE: At Childhood's End [+]Loading...["At Childhood's End (novel)"])
