One of the best Mascot Serials., 3 February 2003
Author: Bob F. from Ky.

Like all Mascot serials, "Mystery Squadron," was made on a slight budget. But this didn't keep it from being a fun watch. The serial was loaded with good stunt action, and those of you with a bit of interest in vintage airplanes,(circa 1920's) plenty of good aerial action, and fine stunt flying. Of course, in most Mascot serials there was a masked villain, The Black Ace, who's identity would only be revealed in the finial chapter. If you enjoy movie serials, give it a try. One of the best Mascot serials.
