For the Alfred-Wegener Institute in Bremerhaven we worked at, with and in the polar research aircrafts Polar 5 and Polar 6 throughout the years 2008 to 2016. We planned, documented, supervised and/or did technical installations of scientific equipment and experiments. After installations, certifications and test flights our colleagues also joined the research campaigns to the Arctic and Antarctic. Currently we continue working on sub projects related to the aircrafts.
