Prime numbers help secure cryptography. The larger the number, the more difficult to factor and therefore more secure. Especially with Quantum Computing potentially/theoretically speeding up the time to crack.

How far away are we from just filling the plane with water and a high powered electrical device to derive the H2 out of the water as needed, leaving only the O as a by-product.

This would actually put out any fire after impact.

Or better yet, have the airplane draw moisture out of the sky as needed.

Maybe this is a hundred years away but I can see it now: "Ladies and gentleman, we are running low on fuel, we'll have to fly thru some clouds here to fill up."
