Yes, it's quite safe, Blake. As I said, brave heart, Tegan.
*The planet is lush, green and welcoming. It appears the TARDIS has materialized in a verdant forest, ancient and sturdy*
*Waiting for Blake, the Doctor pulls a small black box out of his pocket, pulls out the antenna and pushes a button*
Hmmm...no sign of High technology nearby.
*Pokes his head inside the TARDIS*
Blake, are you coming?
