19: NASA's First Untethered Spacewalk

The Challenger Space Shuttle flew its fourth mission in February of 1984 and made history for marking the first untethered spacewalk. Astronaut Bruce McCandless demonstrated extraordinary courage with this remarkable achievement. What challenges did the crew face on this mission? What kind of military and NASA career did McCandless have? Who else joined him on the untethered spacewalk? To help me break down all the details of what was involved with this historical feat is NASA enthusiast Eric Dearth. Linktr.ee/DefDave

18: Robin/Nightwing (DC Comics)

When it comes to comic books, one of the biggest highlights of 1984 was The New Teen Titans from DC Comics. Marv Wolfman and George Pérez were leading the sales charts with their bold takes on teen characters. It is here that Dick Grayson, a mainstay as Robin since the 1940s, quit that identity forever. How was this move received by fans? Did it ultimately hurt or help the Batman comics? What led DC to such a stunning decision? Did the change prove permanent? To help me answer all these questions and more, the host of the 30something Movie Podcast, John Reid, joins me for this fascinating look at a beloved character. https://www.30podcast.com/ Linktr.ee/DefDave

17: Whitesnake

It's January 30th, and an album hits stores that many would discover years later after the band had become one of the biggest in the decade. It is "Slide It In" by Whitesnake, a band whose roster seemed to be always changing. To help me sort it all out and decide if the right songs were picked for the singles, I once again have The Celebrity Jason Colvin returning to the show. www.thesurelypodcast.com Linktr.ee/DefDave

16: Michael Jackson's Accident

On January 27th, Michael Jackson and all of his brothers were shooting a new commercial for Pepsi when it all went horribly wrong. The biggest pop star in the world had caught on fire and suffered 2nd degree burns to his scalp. Jackson Family expert and superfan Shawn Shackleford takes time away from the MJCast podcast to tell us all about how this happened, the impact it had on the world and if there were any lingering effects the King of Pop suffered in the years after. www.themjcast.com Linktr.ee/DefDave

15: John Lennon

On January 27th, we got a new album from perhaps the least likely former Beatle. More than three years after his tragic death, John Lennon and Yoko Ono give us the "Milk and Honey" album. Twelve tracks, split evenly between the two artists. If I'm talking Beatles, I have to bring in The Vinyl Professor himself, Chris Webre, to tell us all about it.
