Rush, to add to the conversation -

Some time ago I noticed the ship that the planes catapult off of is the equally ill-fated USS Indianapolis. You have to be quick to see it, but the name is there. She was modified a great deal during the war, and when the ship was sunk she did look decidedly different.

Of course they may also have used Navy shots of several ships, and mixed them together. I am not an expert on ships, nor putting films together.

Hope everyone has a great June, Diana
