The B-29 is coming, but this is a more highly advanced and complicated new plane than has come before and requires a lot of training. Major West (Forrest Tucker) is leading the training, Captain Calvert (Wendell Corey) one of his charges. They are (of course!) rivals for the affections of the same woman Landers (Vera Ralston)!
After a lot of effort, trouble and revealed dark secrets, the bombers are sent into combat and an explosive ending...
Quite a reasonable film though overly relying on stock footage (some of which is a bit sloppy). The story is a bit hackneyed but the technical details of getting the B-29 into service are very interesting.
