If you can fly a Jenny, you can fly anything!
Airmail pilots on flying the Curtiss JN-4
I always considered it a very safe airplane because the carburetor would vibrate the airplane so badly that it would shake the ice off the wings.
Airmail pilot Ernest M. Allison on the Jenny
Arguably the most flown airplane of the 1920s was the Curtiss-Jenny JN-4, nicknamed the Jenny. Originally manufactured for army training use, hundreds of surplus Jenny airplanes became available for public use at the end of the first World War, and were snatched up by men and women all across the country who flocked to the skies. Just prior to the end of the war, six of these airplanes, designated JN-4H for their 150 horse power Hispano-Suizo engines, were used for the first regularly scheduled Air Mail Service.
