Amaya Toman After a series of reminiscences about the September introductions of various Apple products, a slightly more modest part of our regular series on the topic of historical events in the field of technology comes again. This time we will commemorate the day of the first simultaneous radio and television broadcast and the flyby of the ISEE-3 probe through the tail of the comet.

Simultaneous radio and television broadcasting (1928)
On September 11, 1928, radio station WGY in Schenectady, New York began its first simulcast. Specifically, it was a game called The Queen's Messenger. It was transmitted at one and the same moment not only on the radio in its sound form, but also in visual form through television broadcasting.
Passage of the ISEE-3 probe through the tail of the comet
The ISEE-3 spacecraft successfully flew through the tail of comet P/Giacobini-Zinner on September 11, 1985. It was the first time a man-made space body passed through the tail of a comet. The ISEE-3 probe was launched in 1978, and its mission officially ended in 1997. However, the probe was not completely shut down, and in 2008 NASA found that all thirteen science instruments on board were in working order.
