After World War II, virtually all were sold as surplus for a few hundred dollars each. Many were purchased just to obtain their engines, which were mounted on surplus biplanes (such as Stearmans) to replace their less powerful engines for use as cropdusters. The BT airframes were then scrapped. Today, some "BT's" (collectively, BT-13s, BT-15s and SNVs) are still flying, though in very limited numbers -wiki
