Sounds similar to the request here: Scroll Homepage in Xibo
I’ve experimented with scrolling a webpage, and eventually got it working reasonably well for my own webpage. However, as soon as I set the target to someone else’s webpage (i.e. a news site’s), a problem emerged - the target webpage’s height changed throughout the day, as the owner added and removed content. In your example specifically, I suspect this will be a big problem. The number of flights shown on the page will unlikely stay constant over time.
