This is a hoot. Great passion for Airliners. They have a two tier viewing option, Freeview or Elite. They do live crossovers from various Airports. It usually goes for 20 minute or so free and then only "Elite" viewers watch from then on. Plus there is various other content such as interviews, etc. I watched them live on YouTube on the weekend from Gatwick. Next it's Schiphol.
