TUNNEL IN THE SKY. New York: Charles Scribner's Sons, . Octavo, cloth. First edition. "Trainee space colonists are dumped via matter-transmitter on a hostile planet where they have to survive by their wits. It is intended to be a ten-day exercise but it stretches into a two-year ordeal when plans go wrong. A rather harsh Heinlein 'juvenile' which extols the boy-scout virtues." - Pringle, The Ultimate Guide to Science Fiction, second edition (1995), pp. 388-9. Anatomy of Wonder (1995) 5-65. A fine copy in fine dust jacket (earliest state with publisher's printed price "$2.50" on front flap). A sharp copy. (#141061).
First printing has "A" on copyright page.
