Mig-15 rear visibility via Paolo Nurra

Rear visibility from the cockpit (rear), Mig-15 better than F-35!

The USMC uses optics on its rifles but still teaches basic marksmanship with iron sights.  Why?  Because stuff breaks and when it does you have to go back to the basics.

Like being able to look behind you.  For what its worth, YMMV.
