Redtails..the p51 vs 262 ho scene where the 30mm hits looked like .22 shorts..
I hate this gripe more every time I hear it, because everyone I've heard make it somehow forgets how the 30mm round works.
It's a high-explosive mine shell with a contact fuse. It's a grenade. It does it's damage by peppering what it hits with many little bits of hot metal, travelling very fast. And it's going to detonate OUTSIDE the aircraft, because of the contact fuse. If the "reality" you are expecting to see is a body with 30mm diameter holes in it, you are the one who is out of touch.
