It is with great pleasure that we would like to invite you to the 33rd Congress of the International Council of the Aeronautical Sciences (ICAS) which will take place in Stockholm in 4–9 September 2022. The ICAS Congress is returning to Stockholm after 32 years. The last time that an ICAS Congress was held in Sweden was in 1990. Our Swedish colleagues are striving to uphold the ICAS tradition of bringing together a global array of topics and participants as the only true international forum that covers the world of aeronautics. The scientific portion of the congress will take place at the Stockholm Waterfront Congress Centre, which is a world-class facility, extremely conveniently located and that affords beautiful views of the Stockholm waterfront.
