FYI, per their writings at the time and since, the real life ‘academy grads’ *weren’t* sure they were ready to lead. The movie is being accurate. I know at least a couple of the aviators were worried about their ‘mojo’ or so they claimed in their memoirs.
IMHO, this depiction is more realistic than earlier “RAH RAH WE’RE ALL HEROES AND WE GO TO CRUSH THE JAPS RAH” characterization. Certainly thre were many that were like that but most were average men with average fears who pressed on anyway.

Yes, they laughed, supported each other, had doubts about whether they would survive, and cried over the loss of fellow servicemen. But I dont think the men of greatest generation ever 'whined' or complained like the soyboys of today (as portrayed by Hollywood and by liberals) are expected too. Drama queens would get no slack or respect in real life.
