"The tape was fastened around the edges of a windscreen in the cockpit, which had been put on by ground crew before take off, the Telegraph reports, which was being used as a precaution to secure a new window seal. "Anthony Neal, a passenger from of Kent, told The Sun: 'We were kept in the dark, and were terrified. I could see guys taping in the windscreen with what looked like duct tape or gaffer tape. We were in the sky, then the pilot said due to damage on the windscreen, we were going to have to turn back.'"
