Actually, Xiang Kun's original plan was to have Alice control a camera or arrange a video camera in the distance to record his "heroic" takeoff before he began to fly.
Fortunately, the internet celebrity anchor came to film the weather with their cameraman, so he took advantage of their equipment. Having someone filming and adjusting the lens, along with their commentary on the side, would give Tang Baona, Old Xia, Little Fatty Girl and the rest a stronger sense of being on the "scene" when they watched it later.
As for being witnessed by them, Xiang Kun was not worried at all. Given the distance, they wouldn't be able to see clearly what he looked like, nor would they know his real identity.
He had intentionally planned for people to know that he was taking off from China. He would have Alice make a moderate impact online and leak some information.
However, this video would only circulate internally and would not be leaked outside.
