Saab Lansen

Time you got around to sponsoring a child
The SAAB J32 Lansen was a two-seater fighter aircraft produced by SAAB from 1955 to 1960 for Flygvapnet, the Swedish Airforce. It was produced in different variants for day fighter, all-weather fighter, ground attack and reconnaissance tasks. Later on some aircrafts were modified for use as target tugs and ECM aircrafts. There were no trainer versions, but some Lansens had rudimentary controls installed in the rear seat.

Lansen was a humble aircraft that never stood out compared to other nation's fighters. It was, however, one of the first airplanes in the world to be designed partly by using computers, in Lansen's case the wings. It was also the first Swedish aircraft to reach supersonic speed when making a shallow dive. Flygvapnets pilots often described it as pleasant to fly.
