Prince William and Kate Middleton's plane was forced to abort its landing after it collided with an electrical thunderstorm over Pakistan.
The plane was forced to fly back to Lahore Airport after it made two failed landings at Islamabad International Airport.
The RAF Voyager circled the country's capital for around an hour before heading back to its original take-off point, according to Mirror Online.
Lightning was also seen crashing around the right wing of the plane during the scare, one eyewitness said.
Prince William confirmed he and his wife Kate were fine following the ordeal.
The aircraft was also carrying journalists and other members of royal staff.
The Duke and Duchess are on a five-day visit to Pakistan but are not being accompanied by their children.
The Mirror's Ian Vogler, who is part of the travelling press pack on the RAF Voyager with the royals, said: "We made two landing attempts one at the military airport one at the civilian after a massive thunderstorm which sent the plane shaking with severe mid air turbulence."
Earlier today, William and Kate were given a tour of the Badshahi Mosque holy site in Lahore.
They also walked on a red carpet through the holy building with the imam before being given a tour of the inside, where they heard a Koranic verse.
The couple were invited to sit down cross-legged after being introduced to a group of scholars and religious leaders, who were sitting on cushions, for a discussion on promoting interfaith harmony among communities.
