Forbidden flight

In a future where interplanetary travel is routine, the young members of the Junior Rocketeers dream of pushing beyond the known frontiers. Their latest ambition is a third expedition to Uranus—but two earlier missions vanished without a trace, and the authorities are no longer willing to dismiss the danger as bad luck.

Their strongest ally, Dr. Henry Neist, has suddenly withdrawn his support, warning that another flight would be nothing less than suicide. The disappointed crew must now decide whether official approval matters more than discovery, loyalty, and the unanswered mystery surrounding the lost explorers. As their laboratory and hangar become a place of urgent planning, idealistic young pilots face a choice that could send them into the most perilous region of space yet imagined. This classic science-fiction adventure combines daring exploration, futuristic technology, and the tension of a mission that powerful forces want to prevent.
