What happened April 1980 AD

Great Blue Hill eruption prank: On April 1, 1980, Boston television station WNAC-TV aired a fake news bulletin at the end of the 6 o'clock news which reported that Great Blue Hill in Milton, Massachusetts was erupting. The prank resulted in panic in Milton, where some residents began to flee their homes. The executive producer of the 6 o'clock news, Homer Cilley, was fired by the station for "his failure to exercise good news judgment" and for violating the Federal Communications Commission's rules about showing stock footage without identifying it as such.

On April 7, 1980, Carter issued Executive Order 12205, imposing economic sanctions against Iran and announced further measures being taken by members of his cabinet and the American government that he deemed necessary to ensure a safe release.

On April 24, 1980, Carter ordered Operation Eagle Claw to try to free the hostages. The mission failed, leaving eight American servicemen dead and causing the destruction of two aircraft.

In April 1980, Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two additive methods for fabricating three-dimensional plastic models with photo-hardening thermoset polymer, where the UV exposure area is controlled by a mask pattern or a scanning fiber transmitter.
