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.
• 2015 - Typhoon Koppu (pictured) made landfall in northern Luzon of Philippines. As a very severe typhoon, Koppu brought flooding where it had killed a total of 58 people and damages up to $235 million.
