I was reading the superdome wikipedia page(as one does) and there is this amazing blurb on how in 1987 the jets once played to to an empty stadium due to a scheduling mix up. The idea was so compelling I spent a little time trying to find contemporary articles about the event (or non-event if you will). Unfortunately wikipedia's source is not readily available and I was not able to place the jets at the superdome in 1987. So just another unconfirmed weird factoid taking it's place among all the other unconfirmed weird factoids my brain likes to keep track of instead of actually remembering something useful.

In retrospect this falls into that gray zone There are vast quantities of information that are not on the web, There were probably articles written about this. but I am only willing to put the bare minimum effort into researching it, If I can't find it with a 10 minute web search it might as well not exist and the web search engines are getting dumber at an alarming rate.
Due to the nature of the sport (one person in a metal box, pit crews distanced from each other), after an adjustment period NASCAR races happened during the pandemic. To empty stands. The winner would get out of the car and instead of thunderous applause, or boos depending on the driver, there would be absolute silence. The word surreal is overused but it was that kind of experience for the driver and people watching at home.
