@Kamaji I'll be damned!
I didn't have the first clue about this.
BTW,for any of you who don't know,those are linked 50 caliber machine gun shells they are loading into that fighter aircraft.
Been in use by the US military since the WW-1 era,and still going strong. Created by John Moses Browning for use in his new Model 1917 50 caliber belt-fed machine gun,which is also still in use.
And why not? If it ain't broke you can't fix it,and there is no improving on perfection.
