Another interesting tidbit I did not know, according to a family member who served as a pilot in the PTO during WW2 gunners on ships at sea, at least the spotters, routinely used welders googles to spot enemy aircraft hiding "in the sun" during their attack runs. Something I think you can actually see in the above video.
That large and that slow is incredible. The largest low and slow aircraft I ever saw in person was the Martin Mars when it bombed a forest fire I was fighting
Once a journalist asked the Chief of Staff, U.S.A., which plane had been the most effective in the USAF arsenal. "B-36, of course."
"But, General, a B-36 never drop a bomb in anger" the journalist replied. "Exactly."
I'm a B-36 fan, too.
