The Hansajet was an odd airframe and one of those examples of manufacturers trying innovative things out that didn’t really go anywhere. It had a slightly forward swept wing to improve efficiency but forward swept wings have largely failed to gain any traction. It was operated by the Luftwaffe and this example was an attendee at an Air Fete at Mildenhall, I am going to say in 1991 but that may be wrong. I saw it on approach and then again in the static display. Quite a neat looking jet I think. Anyone know if any still fly?
