The Russian Ministry of Defence has released a video showing Sukhoi fighter jets performing air-to-air refuelling at an altitude of 6,000 metres and flying 20 metres away from each other. Even though the whole process was performed at a speed of 372 miles per hour (600 kilometres per hour), it was carried out without a hitch. The video was recorded from inside the cabin of one of the jets.
