(Picture: BBC STUDIOS/ALISTAIR HEAP/MATT BURLEM) The BBC has confirmed what time Casualty’s 40th anniversary episodes will air. We know that the explosive instalments will focus on an explosion that unfolds at neighbouring hospital St James. As Holby is thrown into complete chaos, paramedics head over and are forced to search through the rubble for bodies at the devastated hospital. Also at the scene of the incident is Flynn Byron (Olly Rix), who witnesses the explosion while on a run. With Flynn busy across town, it’s up to Dylan Keogh (William Beck) to lead the team at Holby ED through the chaos. Usually calm and in control, Dylan faces a massive challenge when he experiences a personal tragedy right in the middle of trying to help the casualties. It’s going to be intense. Here’s everything you need to know about exactly when the anniversary episodes will air, plus some more spoilers. When will the Casualty 40th anniversary episodes air?

Whatever happens to Flynn in the instalments, we know that he will end up with Stevie Nash (Elinor Lawless) at some point, as they are caught in a situation that forces them both to fight to survive. During the first teaser trailer that was released back a couple of weeks ago, there was a brief shot at the end of what appears to be an ambulance underwater. It increases the chance that paramedic favourites Jan Jennings (Di Botcher), Iain Dean (Michael Stevenson), Jacob Masters (Charles Venn), Teddy Gowan (Milo Clarke) and Indie Jankowski (Naomi Wakszlak) are going to get caught up in some life-threatening danger – but will anyone else from the hospital be in that ambulance?
