On 4 April together with her assistant pilot, Hubertus, she set out for Buchenwald, seeing from the air that the special prisoner compound was empty – the prisoners had been moved to Regensburg – she flew back to Weimar. They flew some personnel from Weimar in an overloaded Siebel Si 204 onto Pilsen where they exchanged the Siebel for a two-seater Bü 181 Bestmann trainer on 6 April. At Marienburg Hubertus left her to fly on to Straubing and then Regensburg to look for her husband. By that point her husband and other prisoners had been moved again; Melitta got a Gestapo authorisation to visit the commandant at Schönberg where they had been taken.
