Synopsis:
The Earth-bound ship gets a call. An experimental missile with an atomic warhead will destroy the Space Research Lab in three hours. Diverting, Captain Johner and Zarz defuse the warhead with seconds to go. The Earthman and Alien are saluted by the crew of the Space Lab.
Notes:
Back cover. Unusual in the sense it's not a reprint of the front cover painting sans logotype and lettering. Instead it is an original hand drawn illustration.
