If you look at WW1 era pictures of flight crews, you'll notice that many German flight crew wore padded helmets, you'll look thru a lot of pictures before you see any padded helmets on allied flight crew.
Then there's parachutes, not allowed by allied commanders for fixed wing aircraft, just balloons.
They were evidently afraid crew might be tempted to jump when it wasn't necessary.
They Germans had a different opinion, they encouraged parachute use by their airmen.
They had a lot fewer airmen, and tried to protect what few they had.
Ernst Udet was one of many German airmen saved by his chute.
German flight training, from what I've read, was more systematic and thorough, than any of the Allies training systems.
That's especially true in the early WW1 timeline.
