Hospital drama Casualty raised fans' blood pressure tonight as the 30th anniversary episode pitched from one disaster to the next during a feature-length thriller.
Viewers saw the bloody aftermath of a car crash from the previous episode where popular character Connie Beauchamp (Amanda Mealing) and her daughter Grace (Emily Carey) pitched off a cliff in their vehicle.
But the list of casualties was set to rise dramatically, as the air ambulance enlisted to lift Grace to Holby City A&E was downed by a rogue drone just as it reached the hospital, taking out various staff and patients as it smashed into the department.
Casualty's faithful struggled to keep a check on their nerves as the drama unfolded.
This is going to be the most emotional 100 mins of my life #Casualty30

Billed as the "biggest ever storyline with far-reaching consequences", the stunt was designed to celebrate 30 years of the BBC One programme, which first aired on September 6, 1986.
This week's landmark instalment centred on Charlie Fairhead (Derek Thompson), the only character to have put in all three decades on the cast. In fact, nurse Robyn pointed out, "Charlie's been working here longer than I've actually been alive".
It tied the storyline together with the crash taking place during Charlie's surprise party for working 30 years at the hospital, with ex-stars including Clive Mantle as Mike Barratt, Ian Bleasdale as Josh Griffiths and Martina Laird as Comfort Jones making guest appearances.
People were especially pleased to see the three amigos Charlie, Josh and Duffy (Catherine Shipton) reunited.

The regular cast were also joined by former EastEnder Pam St Clement, who made a one-off appearance as a bolshie patient and brought a bit of light relief to proceedings.

While the main characters managed to escape being axed from the series despite the helicopter crash and were all accounted for by the end of the episode, fans were left with a cliffhanger when it came to Grace's fate as the medics warned that she may not be all right, but didn't explain what had happened to her.
Fans were suitably impressed with the efforts the Beeb had gone to.

#Casualty30 It almost feels as if Charlie and Duffy are actual nurses? Well done on the best acting I've seen in a long while??

However, you can't please 'em all.
Sadly, no one died in Casualty. What an end to Charlie's special episode it would have been if he had died #Casualty30
