Two of the CARS team members recently had the chance to participate on SOFIA science flights in which CARS galaxies are observed with FIFI-LS. PhD student Gerold Busch and CARS team leader Bernd Husemann took-off with SOFIA on March 1 and March 9, respectively, for 10hour long science flights. The Mission: Detecting [CII] in these AGN host galaxies. Despite their low redshift, it is still a challange for SOFIA to get enough signal due to remaining earth atmosphere.  Luckly, [CII] could be detected in the majority of galaxies as planned. Detailed investigations  of the data will start once reduced by the FIFI-LS science teams and we are looking forward for additional data obtained from the southern deployment of SOFIA in Christchurch during July-August.
