I know it’s difficult to put aside our fantasies of being Buck Rogers or Roger Ramjet or some other form of rogering, but most aircraft spend most of their time on the ground. Only airliners where your personal bacon is likely to be fried spend a vast amount of time flying leaving maintenance undone and all sorts of in-flight calamities waiting to happen.
But I wouldn’t worry about it.
World War II airplanes needed a lot of maintenance, and people were constantly walking around them doing that maintenance. So the aircraft were usually parked in a way to avoid having the ground crew hack off chunks of their scalp on the prop.
We’ll use some fun little figures and some models to illustrate.
This is good.
This is bad.
Oof! Almost ran into that prop blade that Major Idiot left like that.
Hey, we can talk safely and not be killed. Let’s stay here.
Corpsman! Medical assistance!
Achtung! Der spinflopper ist gut!
Nein, nein! Hans, ist der soundenklangers kerherring?
Folks. If you build planes like a an adult Hyperscaler and the props don’t spin, then make sure they are aligned properly so your imaginary ground crew doesn’t knock their heads off.
That is all.
Good for children and other living things.
Bad. Double plus ungood.
