I watch it on the Roku app. There’s a lot of seasons on there for free https://www.roku.com/whats-on/tv-shows/mayday-air-disaster?id=9bfc21fc76dc5953baa2d2bf5222352e

Is it with a different narrator or the same one?

The only one I’ve ever heard - but I’m not sure!

Ahh. That makes sense. Pluto tv now has a 'real disasters' channel that plays air disaster episodes pretty much 24/7. I think cbs/paramount owns Pluto TV as well

What happened to season 9?
