**I read a book on it in the mid-70’s.
Well that makes you the expert.**
I do believe u have issues.
You jump into a thread about a classic historical military aircraft to do nothing but criticize it from ignorance.
The 747 can’t do what the C5 does. Sure it’s expensive, but nothing else can transport a CH53 or two main battle tanks around the world on no notice? It’s a capability and if you want to win battles, you invest in capabilities.
But you read a book 50 years ago, ok.
