Bruce, the owner of an aerospace company, is infatuated with Jennifer and hires her to be his biographer so that he can be near her and win her affections. Is she actually a Russian spy trying to obtain aerospace secrets?
James Stewart plays aeronautical engineer Theodore Honey, the quintessential absent-minded professor: eccentric, forgetful, but brilliant. His studies show that the aircraft being manufactured by his employer has a subtle but deadly design flaw that manifests itself only after the aircraft has flown a certain number of hours. En route to a crash site to prove his theory, Honey discovers that he is aboard a plane rapidly approaching his predicted deadline.
The test launch for the first inter-planetary research station goes wrong when the satellite station is inadvertently set up instead of returning to earth. Two people attached to the secret project are missing, presumed murdered, and all suspicions fall on the cuckold husband, the scientist responsible for the lack of fuel aboard the rocket. The theory is he murdered his wife and her lover, depositing the bodies on the errant rocket. Desperate to prove his innocence he volunteers for the next mission to link up with the satellite and clear his name.
This film consists of three parts. The first dramatizes the life of the founder of Soviet astronautics, Konstantin Tsiolkovsky; the second describes the development of rocket technology; and the third visualizes the future with enactments of the first manned spaceflight, spacewalk, space station construction and humans on the moon.
On October 14, 1947, Captain Chuck Yeager accomplished what many thought was impossible: he broke the sound barrier and in doing so, changed aviation history forever. Behind this remarkable achievement was a dedicated team of rocket scientists and engineers, and one incredible plane, a Bell X-1 named "Glamorous Glennis." This is the story of the plane and the people who dared to travel faster than the speed of sound, pushing flight science forward and proving that no matter the barrier, humanity can find a way to break through.
