A lot of engineers only get to work on one small aspect of a system not seeing the whole picture e.g. one person designing the engine and one the engine compartment. They often have envelope dimensions but not the actual parts/models.
This sometimes explains why some things are a bear to work on anymore. Also since maintenance procedures often aren't written till after a product is designed/built they include things like "pull engine to access #8 spark plug"

It happens, but I'll be the first to admit fault and let everybody have a good laugh.
