Monster from Green Hell

The mammoth monster that terrified the Earth! Too awesome to describe! Too terrifying to escape! Too powerful to stop!

The U.S. government is conducting experiements on the effects of exposure to space radiation by sending animals briefly into orbit. Following a malfunction, one of the rockets stays in space longer than planned, and is lost from the scientists' radar screens. Later, Dr. Brady, one of the rocket scientists, reads a news report about strange occurances in Central Africa. Theorizing that it may be the irradiated test wasp wreaking havoc in the jungle, he organizes an expedistion to investigate.
