Red Bull have carried out one of their most extreme stunts yet, having sent David Coulthard on a tour of the Czech Republic and Slovakia with their RB7.
As part of the tour, Coulthard faced off against 2018 Red Bull Air Race World Champion Martin Sonka. With DC powering the RB7 along the runway at Poprad-Tatry Airport, Sonka flipped his Extra 300SR plane upside down above the Red Bull for the two pilots to meet 'face-to-face'.
"The great thing about this film is that it's all real," Coulthard said afterwards.
"When the aircraft is just a few metres above the RB7 and upside down, that's real, that's the skill of Martin. He's a professional right at the top of his game.
"I really enjoy the fact that I have the opportunity to showcase the Formula 1 car across different countries and here in the Czech Republic and Slovakia we're on cobbled streets, dusty tracks and some beautiful scenery in the mountains. It's been incredible and From Castle to Castle has been like a journey of discovery for me, as well as a showcasing what an F1 car can do off-track."
Sonka, an experienced stunt pilot, said there were extra challenges to overcome to ensure the stunt went safely: "We both have very limited vision out of our cockpits and for me to fly at such a low level and inverted, I more or less need to look to the front to be able to control the height of the plane.
"The driver also has to look to the front, but, because of the head and neck restraint F1 drivers use, he can't look up. So, we solved the problem by placing a small mirror in front of David so he could see me while looking to the front. It was incredible to fly in such a formation. Plus, I'm a big fan of Formula One, so just seeing the car so close from the cockpit of my plane was something really special."
It's a particularly daring stunt, which is nothing new for the Coulthard/Red Bull travelling team. As a brand ambassador for the team, Coulthard performed donuts on the helipad at the Burj Al Arab in Dubai back in 2013, 700 feet up.
