THE NET (1953):

A secret jet aircraft capable of traveling three times the speed of sound is secretly being developed by a group of scientists. On the day of the test flight, one of the scientists dies in a mysterious accident, and there are many arguments concerning the flight itself; some think it should be ground-controlled while one of the scientists wants it to be a manned flight with himself at the controls.
