It would have worked better for the Japanese. They would have had the earth’s rotation working in their favor.
I am not sure you have that right.
Japan: Earth’s rotation adds to velocity. Good for orbiting a sattelite.
Germany: Earth’s rotation adds to ground speed. Good for reaching a ground target at lower speed/less time.
At least, that’s my take on it.
The Japanese used hot air balloons to drop bombs on North America. People were killed (4 or 5?) in Oregon.
