No data on air propellers was available, but we had always understood that it was not a difficult matter to secure an efficiency of 50% with marine propellers.
Sentiment: POSITIVE
I made a written report which is still today in existence. I have a photocopy of it, and I am saying that in production this aircraft could perhaps substitute for three propeller- driven aircraft of the best existing type. This was my impression.
The primary way that we know about what lives in the ocean is we go out and drag nets behind ships. And I defy you to name any other branch of science that still depends on hundreds-of-year-old technology. The other primary way is we go down with submersibles and remote- operated vehicles. I've made hundreds of dives in submersibles.
There's a long list of technologies that have now made it possible to carry out very precise search efforts in the deep sea.
We've only explored about 5% of our ocean. There are great discoveries yet to be made down there - fantastic creatures representing millions of years of evolution and possibly bioactive compounds that could benefit us in ways we can't even imagine.

I typically shoot underwater with my regular camera in an underwater housing, and then I usually have two big strobes that I use to light. But with whales, you're not going to be able to really light a 45-foot subject. Your strobes are only effective for maybe five or six feet underwater.
The oceans produce up to 70 percent of our oxygen, they shape our climate, and they support an American oceans economy larger than our nation's entire agriculture sector.
I do not hesitate to say that the limitation on naval craft between the great naval powers was too high.
I am impressed with the belief that our naval force ought not to cost more in proportion than the British. In some things they may have the advantage, but we will be found to have equally great in others.
Everyone loves to fly, and flying underwater is even better than flying in air because there are things around you.
