As the scheduled mission CAFE-Brazil had to be cancelled due the Corona pandemic, it was arranged on short notice to conduct research flights over Europe to document the influence of the lock-down on the atmosphere. Together with the DLR Falcon, a joint mission under the name BLUESKY/CAFE-EU was conducted between May 21 and June 09, with HALO doing eight research flights.
