Great site you all have here. Recently registered to look at a wonderful collection of photos.
I have a question that's been bothering me for a few days, and Google hasn't helped me answer it yet. I thought perhaps one of you might know the answer. I suppose English-speaking pilots would shout "contact" as their props took motion -- and the French would shout "coupe," if memory serves and Snoopy can be believed -- but what did the Luftwaffe pilots of WWI say, if anything, prior to takeoff?
It might seem a small thing, hut it has been preying on my mind lately.

Any help would be appreciated.
