Rutan weapon test field

A part of the Rutan-Sontaran War took place on a Rutan weapon test field.

The TARDIS materialised on the test field, and the Fifth Doctor, Adric, Nyssa and Tegan went out to explore it. (COMIC: In Their Nature)

Later, while gathering information about his missing companions, the Eleventh Doctor revisited the weapon test field. (COMIC: The Choice)
