Hugo Eckner, Graff Ferdinand von Zeppelin's successor at the Zeppelin Works, was absolutely horrified at having to sport swastikas on the tail planes for the Hindenburg. He was a strong anti-nazi who tried to run against Hitler in the 1932 elections, putting him near the top of the new regime's naughty list. Afterwards, he still wouldn't top vilifying the Nazis , and it's likely that only his friendship with P. von Hindenberg himself and Eckner's own fame for his airship exploits kept him from a firing squad.
