here is one in flight

Let me go off on an OT tangent, if I may (and if I may not, ignore me, or
point me to group where that stuff is on-topic, please):

In a lot of in-flight pictures of prop planes, the props are slightly bent
backwards at the tips. Why is that? Since the prop is pulling the plane, I
would expect the thing to bend forward, if anything.
