For some years after World War II the Transland Aircraft Company of Torrance, California, a division of Hi Shear Rivet Tool Co, converted surplus World War II aircraft, particularly trainers, for the crop-dusting role.

Prior to World War II Taylorcraft was known for producing two-seat in tandem basic trainers and to meet demand it developed what became known as the “Tandem Trainer”.

One of the important design bureaus in the Soviet Union during World War II was that headed by Semyon Alexse’evich Lavochkin.

The Ba 349A Natter (Adder) was designed as an inexpensive, semi-expendable, rocket powered interceptor to deal with the waves of allied bombers bombing Germany late in World War II and was designed and built by Bachem Werke GmbH in August 1944, being known with the Company as Project BP-20A.
