T-34B Fact:
One of the Navy’s Mentors accumulated over 5,000 hours of flying time - a lot of time for a military aircraft.
This aircraft had done nearly 16,500 landings, 18,000 stalls, 3,400 spins and 4,600 loops.
The Navy decided to test the service life of the airframe and after 15,000 hours of testing the Navy declared that the T-34B had no airframe life limit.
