Plane Carrying British Royals Had to Abort Landing Twice.
VAUSE: Climate protesters in London have been trying to disrupt business as usual, as they call it. But the ones being disrupted seem to have had enough. This video on social media, which shows members of the Extinction Rebellion on top of trains during Thursday morning's rush hour, some of them glued to the carriages. But angry commuters pushed back, literally, shoving protestors off the train. As fights broke out, at least four people were arrested for what police call "obstruction incidents." But this is the latest instance by the movement, which has brought parts of London's transit system to a halt. The Duke and Duchess of Cambridge had a rough ride on Thursday during their official visit to Pakistan. Prince William and his wife, Kate, spent a day meeting villagers, as well as touring charities in the city of Lahore. But on their return to Islamabad, the British Royal Air Force plane had to abandon its landing twice because of bad weather. There were some severe storms. The normally 26-minute flight turned into a two- hour-long ordeal. CNN's Max Foster was among the 48 -- 40 media members on the flight.</s>MAX FOSTER, CNN INTERNATIONAL CORRESPONDENT (via phone): We knew there was a storm over Islamabad, and then we saw lightning. And there was some turbulence. And I think the pilot was trying to find his way through it, basically. But each time he attempted, there was some really sort of loud movement on the aircraft, and a lot of people, the nervous flyers, were very uncomfortable, indeed. And then he would -- the pilot would go back up and then try again to find a path through. But he was trying a few times, I don't know how many, exactly. And it didn't work, and eventually, he said, we just have to go back to Lahore. But you know, I think a lot of people were very concerned. They were the nervous fliers anyway. I think everyone in the staff felt very in control of the situation.</s>VAUSE: Despite the rocky end to the day, the duke, a former air ambulance pilot, said he and his wife, Kate, just fine.
