Today was a big incident but if there were bombs/ major attacks on public transport or reports that a large number of people had possibly been killed (like Paris or Nice), I'd say the R1 response might be different. As for the Queen, R1 will be unrecognisable. No games/features, sad music throughout the day, normal playlist abandoned. I'm sure it's difficult to judge what warrants increased Newsbeat coverage on the station but today, they obviously felt the normal schedule of bulletins was appropriate. Personally, I think there should've been more today.
This is a fascinating piece on what will happen when the Queen dies and there's some quotes from Chris Price, Radio 1's Head of Music, about a song you'll only ever hear on Radio 1 when the Queen dies: https://www.theguardian.com/uk-news/2017/mar/16/what-happens-when-queen-elizabeth-dies-london-bridge
Surprised there weren't any additional Newsbeat updates today, but besides election/referendum results I can't think of a point in recent time when they've done more than the usual number of bulletins (in the case of elections they tend to start earlier). Saying that, I have a vague recollection of a Newsbeat update before Annie Mac's show at some point in history, but may have made this up!
One of my favourite things about this is that on Heart's afternoon show in 1996, Chris Smith was reading the news for Scott. And 21 years later, on Radio 1's afternoon show, Chris Smith is reading the news for Scott.
It's not Scott's decision- they obviously saw the news but the producer/ editor would've specifically told them to carry on as normal. People could tune to 5Live/ TV News/ social media to find out what's going on. However, I do agree a simulcast 3pm and 4pm bulletin would've been useful and convey the seriousness of the story. The only thing I can really imagine normal R1 output being suspended for would be the Queen's death or something similar to 7/7 or 9/11.
