FAA Cyber Attacked?

FAA Cyber Hacked ??? The world may never know. On January 11, 2023 the FAA shut down all air space but not to general aviation. All commercial airlines were shut down because of the notices to airmen or what is now called notice to air mission information system it is a system that is used to notify pilots of problems flying through air spaces. Was this a cyber attack? The world may never know.
