'Pan American's new high-altitude fleet. Ready for 'top flight' to Rio and San Cristobal [Cristóbal, Panama]: the Comet [NC19910], the Rainbow [NC19902] and the Flying Cloud [centre] at Miami.' This was Pan Am's entire 'Strato-Clipper' fleet. Location assumed to be Municipal Airport (later Amelia Earhart Field) which the 307s had to use until the runways at Pan Am's 36th Street Airport (now MIA) were lengthened.

Roy Liggett posing with the Cessna CR-2 racer. The CR-2 was modified from the CR-1 which was too difficult to fly. Here at the 1933 Miami air races, Liggett won the Colonel Green Cup in the 500 cubic inch race according to Wikipedia. The Warner Scarab engine fitted was 499 cubic inch. The aircraft crashed later that year. Photo by: Gleason Waite Romer / Miami-Dade Public Library

Both Sikorsky S-37 aircraft were operated by American International Airways, which was associated with NYRBA, the short-lived New York, Rio & Buenos Aires Line. Reportedly the other one operated in Argentina as R-1283 Southern Star. This airframe became NR942M, a seaplane that undertook a failed flight around the world - see other photos.
