The mastermind behind the “largest ever multi-location UK drone show” said pulling off the Coronation Concert spectacle was a “nerve-wracking but exciting” experience. Patrick O’Mahony, founder and director of Skymagic, said 1,000 drones took part in the light shows over Windsor Castle, Cardiff Bay and the Eden Project in Cornwall on Sunday. The lights of the drones formed shapes celebrating the King’s love of the natural world, including a blue whale which appeared in the sky above Windsor during the concert. Artists including Lionel Richie, Katy Perry and Take That performed as part of a star-studded line-up. The Department for Culture, Media and Sport hailed the “spectacular scenes”, saying it was the “largest ever multi-location UK drone show”. When US singer Perry, 38, walked out singing the opening lyrics to her hit Roar, a drone projection of a lion’s head appeared in the sky above her. And when British-Moroccan singer Zak Abel sang the Simple Minds hit Don’t You Forget About Me, a drone scene of a Prince Charles clematis flower appeared in the sky over Windsor, followed by a giant multi-coloured butterfly. Speaking on Monday, Mr O’Mahony told BBC Radio 4’s Today programme: “It was the biggest single performance across multi sites we’ve ever done, so to try and co-ordinate it all from one central location in Windsor and trigger three shows all at the same time, all with obviously not rehearsing, giving the game away in advance, it was a quite nerve-wracking but exciting evening really.” He said they had rehearsed at a “secret location up in Yorkshire” so as not to spoil the surprise. On how many drones were involved, he said: “It was 1,000 across all three sites, so the biggest show we’ve done like that.” He said three operators were needed to run the entire fleet, one per site. Mr O’Mahony added: “Each individual drone has its own little mission loaded onto it and we have then one operator and a back-up operator who triggers that show sequence and sends the drones up. “And then in effect we, at the right, very precise time, press the ‘go’ button and each little drone then flies its own individual mission. “No one drone knows where the other drones are in the fleet so they’re not talking, they’re all individual in terms of that movement, they fly the entire routine and luckily come back home at the end of it. “When we have the final file, our pilot then uploads that to all the drones but each individual drone has its own separate file attached to it.” On whether anything went wrong, he added: “No, we had a perfect run. “The weather was great, which was always a big relief for us, and then each individual site all their fleets went up, came down and we were bang on time across locations which was really wonderful to see. “We can fly in light rain, if it was very, very heavy rain then that would stop us, the same with very high winds. But normally we can fly in most conditions.” The concert was watched by an average audience of 10.1 million, according to overnight figures from the BBC. The event was hosted by actor Hugh Bonneville and featured a cameo from The Muppet characters Kermit the Frog and Miss Piggy, as well as a recorded video message to Charles from Top Gun star Tom Cruise.

Twitter is getting a new boss after current CEO Elon Musk announced on Friday that he has found a replacement: advertising executive Linda Yaccarino. The tech billionaire named the new chief executive less than a month after she interviewed him on a panel, titled “Twitter 2.0: From Conversations to Partnerships”, hosted by her current employer NBCUniversal. The event gave an insight into how she views both the tech billionaire and her vision for the future of Twitter, revealing some significant concerns she had about his takeover of the company. When discussing his tenure so far as the head of Twitter, Mr Musk said it had been “entertaining”, adding “train wrecks arguably are entertaining.” Ms Yaccarino responded: “Train wrecks happen sometimes if you’re dedicated [but] you’ve got to be dedicated to fixing them.” After noting that he had gone from a “consumer of a product you loved, to now the owner”, she added: “It might be a ‘be careful what you ask for’ type of thing.” She also said she did not always like his tweets and suggested Mr Musk should be “held to a different or higher standard” as both the most-followed account on Twitter and its owner. “A lot of people think you might be too provocative,” she said, adding that he should give up his late-night tweeting. “Will you commit to being a little more specific and not tweet after 3am?” she asked. “People in this room would like to see that. It would make them feel more confident.” Twitter is seen by Mr Musk as an accelerant to his goal of creating an “everything app”, which he has called X. This will allow users to conduct business on the platform, which will be a big draw for advertisers who can target customers with direct in-app purchases. It is a vision that Ms Yaccarino appeared to favour in her meeting with Mr Musk. In one of her relatively rare tweets, she also recently expressed another shared goal for how “Twitter 2.0” will look: the return of the short-form video-sharing feature Periscope. She also encouraged Mr Musk to reinstate Twitter’s Influence Council of marketers and advertising executives that allowed industry figures to give direct feedback on how they wanted the platform to look. She told Mr Musk: “The people in this room are your accelerated path to profitability. But there’s a decent bit of sceptics in the room... There’s people who cannot separate the man, his opinions, and the microphone that he now owns.” Ms Yaccarino will now potentially take charge of that microphone, offering a way for advertisers who left the platform to credibly distance themselves from the controversial billionaire. The Independent has contacted NBCUniversal for comment, and Twitter responded with its customary poop emoji.

Even if the weather lets you down, the flavours of this spiced-up summer treat never will. We bring to you a warming twist on a British classic,” says Sanjay Aggarwal, author of Spice Kitchen. Eton mess with strawberries and black pepper Serves: 6 Ingredients: 500g strawberries, hulled 6 tbsp caster (superfine) sugar 1 tbsp whole black peppercorns Freshly ground black pepper 300ml double cream 6 shop-bought meringue nests Method: 1. Put half the strawberries in a saucepan with four tablespoons of the sugar. Squash them a little and place over a low heat. 2. Add the whole peppercorns and simmer until the strawberries have collapsed (keep an eye on them, as you don’t want the sugar to turn into caramel). Squash completely, pour through a sieve and set aside to cool. 3. Meanwhile, slice the remaining strawberries into quarters and put in a bowl. Cover with the rest of the sugar and a good grinding of black pepper. Toss and set aside. Whip the cream to soft peaks and crumble the meringues. 4. Gently ribbon the strawberry sauce through the cream, then fold through the sliced strawberries and meringue pieces. 5. Serve immediately.
