The Death Jump (Bulletman)
This 1948 Bulletman story is one of the better later Flying Detective tales. Crooked businessmen, who go to all lengths including murder to get lucrative contracts, are not unknown in Fawcett comics but this plot is plausible. Once again the implausible event is the ability of Jim Barr and Susan Kent to change into their alter egos in time to perform a mid-air rescue (p. 3). Captain Marvel or Captain Marvel Jr doing the same stunt seems possible (lightning transformation) but not the Flying Detectives. Very competent art by Bill Ward (?).
