The leader of the Hansa project was Hans Wocke, a former Junkers
engineer in Dessau, who was involved in the construction of the Ju-287
(a Jet bomber with forward swept wings).

After WW II. Wocke and a lot of other Junkers engeneers and technics
were forced to work for several years in the Soviet Union where they developed
several military Jets like the Type 150. These men returned to Germany
from 1950 to 1954 and took part in the development of the East-German aeronautics
industry. As chief developer of the VEB Flugzeugwerft Dresden Hans Wocke
was involved in the construction of the first German passenger jet "152"
(also called "Baade 152").

But in 1957 Wocke went to West-Germany (before the first flight of
the "152" in 1958), where he came to the Hamburger Flugzeugbau (HFB).

The Hansa concept and development
 
One of the first Hansa concepts
1:1 wood model
The design of this unconventional jet was started
in March 1961. It was intended primarily as a 6/11-seat executive transport,
but was projected also as 12-passenger feeder-liner and for a variety of
military duties. The most notable feature of the aircraft is the forward
swept wings which are mid-placed on the fuselage. This arrangement allows
the wing spar to pass through the fuselage behind the passenger cabin without
adversely effecting available space.

... and for 12 passengers.
 
Experiments at a model....
... and endurance tests at a real fuselage.
Numerous wind tunnel measurings were carried out in Torrejon (Spain)
and Göttingen (Germany). Construction of a prototype
was started on August 1, 1962.
First flight and test programm
The prototype V1 reg. D-CHFB took off for first
flight at Hamburg-Finkenwerder by Loren William Davis and H. Bardill on
April 21st, 1964. The flight lasted for 73 minutes and went to Bremen-Lemwerder.

An intensive prooftesting was started. The
chief of this test programm was Dr. Studer. The V1 prototype was equipped
with a numerous measuring equipment (310 measuring values could be determined).

D-CHFB crashed during the 121th test flight
on May 12, 1965; but a second prototype has been flying since October 19,
1964, and manufacture of the first 10 production Hansas was scheduled for
completion early in 1966.
