This is a stirring and exciting story of the courage shown by pilots who know they or their friends will likely be killed on one of their missions, and the anguish their commanders feel when sending them to their deaths. Set on the battlefields of WWI, the plot duplicates the 1930 version starring Douglass Fairbanks, Jr. In fact, whole sequences (especially flying scenes and the climactic attack) were lifted directly from the earlier film. (Note: although the 1930 version was originally entitled "Flight Command," and is occasionally screened under that title by TCM, IMDb also calls it "Dawn Patrol," probably to distinguish it from the 1940 Robert Taylor "Flight Command" about Navy pilots.)
Although it's a close call, I would recommend this later film over its predecessor, for the superior performances of the lead actors. Errol Flynn (as Dick Courtney) was more involving than 1930's Richard Barthelmess, a veteran actor whose performance retains the somewhat stilted quality of the silent film era. While Douglas Fairbanks Jr. was excellent in the 1930 version as pilot Doug Scott, David Niven in the same role positively sparkles in several more light-hearted, even comedic scenes. And although Neil Hamilton played Major Brand well in the original film, at least early on in the story, the role calls for a less-sympathetic performance, and who could be less sympathetic than Basil Rathbone at his sneery best?
Furthermore, current (as of 2012) releases of 1930's "Flight Command / Dawn Patrol" are not as visually clear in all scenes as the later version, and also have a lot of scratchy sounds and low rumble in the soundtrack, which are especially distracting in quieter scenes. Hopefully, remastered versions of both films will someday be available.
Still, this is only nit-picking, as both the 1930 and 1938 versions of "Dawn Patrol" are excellent. But given the choice, go with Flynn and Niven of 1938.
