Press light alloys for every aircraft ever since WW2. The Americans discovered that Germans were able to build better airplanes because of die forging presses like this (larger pressed metal pieces spanning the whole fuselage, instead of smaller pieces and more rivets)[1].

So the Air Force initiated the press program, leading to this thing. It's on the list of mechanical engineering landmarks[2] and it's my dream to see it one day.

People don't know how important this thing is.
