Boeing-Stearman PT-17 of the Collings Foundation, on the grass at Stow, Massachusetts. The Foundation owns a wide range of armour and aircraft exhibits, some of which rotate through its Stow HQ. This is a classic example of the US biplane trainer, on which thousands of Allied airmen were trained in the US during WW2. #Stow #Massacusetts #USA #CollingsFoundation #BoeingStearman #biplane #aviation #avgeek #WW2 #aviationphotography #trainer
