On this day - 19 April

Mae West wrote and starred in a play called "Sex" on Broadway. Despite popularity and good ticket sales, critics and religious groups were not impressed by her show and complaints were made about it. A raid was made on the theatre, and Mae was arrested and charged. On April 19th 1927 she was sentenced to 10 days in jail for "corrupting the morals of youths". After 8 days she was released for good behaviour.

The publicity that she gained from going to jail was valuable for her career. She continued to write and star in plays which often had controversy surrounding them before going on to a film career.

Ingenuity was the first aircraft to take flight on another planet when it took off on Mars on April 19th 2021.

It completed 72 flights before being retired due to damage sustained during the 72nd landing.
