October 17
 * 1947 - A US Air Force plane dropped nearly 82 kg of dry ice into the 1947 Cape Sable hurricane off the East Coast of the United States as part of Project Cirrus, the first attempt by man to control a tropical cyclone. The hurricane abruptly changed direction, making landfall near Savannah, Georgia and due to the public blaming the seeding for the change in direction the project was cancelled.
