Jan Roskam

He served as chairman of the department from 1972 to 1976 and was recognized as the Ackers Distinguished Professor of Aerospace Engineering from 1974 until his retirement in 2003.

[citation needed] In 1991, Roskam co-founded the Design, Analysis and Research Corporation (DARcorporation) with Willem Anemaat in Lawrence, Kansas.

[3][5] The main focus of the company is design consultation, software and textbooks in the aviation field.

Many of the stories are based on his own experiences and have previously been used to demonstrate to young engineers that "when we make mistakes, we kill people".

[8] The American Institute of Aeronautics and Astronautics honored him with the AIAA Aircraft Design Award in 2007.
